+## Filing an issue
+
+Before filing an issue, please [search the queue](https://github.com/c3js/c3/issues) to make sure it hasn't already been reported.
+
+If a bug, please include the following —
+
+1. What version of C3?
+1. What browsers have you confirmed it in?
+1. Can you isolate the issue by providing a jsFiddle demonstrating it in a minimalist capacity?
+
+Please *do not* ask for support using the issue queue. For support, please ask [on chat](https://gitter.im/c3js/c3) or [the mailing list](groups.google.com/forum/#!forum/c3js).
+
+## Setup
+ 1. **Clone the repo from GitHub**
+
+        git clone https://github.com/c3js/c3.git
+        cd c3
+
+ 2. **Acquire build dependencies.** Make sure you have [Node.js](http://nodejs.org/) installed on your workstation. This is only needed to _build_ C3 from sources. C3 itself has no dependency on Node.js once it is built. Now run:
+
+        npm install -g grunt-cli
+        npm install
+
+    The first `npm` command sets up the popular [Grunt](http://gruntjs.com/) build tool. You might need to run this command with `sudo` if you're on Linux or Mac OS X, or in an Administrator command prompt on Windows. The second `npm` command fetches the remaining build dependencies.
+
+## Building C3 from sources
+    npm run build
+
+
+## Distribution
+    npm run dist
+
+Now you'll find the built files in `c3.js`, `c3.min.js`, `c3.css` & `c3.min.css`.
+
+## Running the tests
+    npm run test
+
+This command will automatically run the specification suite and report its results.
+
+If you want to see specs running live in browser (e.g., for debugging), simply open `http://localhost:9876/` in your browser when phantomjs starts.
+
+## Building the document site (c3js.org)
+
+First you need ruby and [bundler][] to build the documentation site.
+
+**Note:** Currently the site doesn't build with ruby 2.5.x, so you need ruby 2.4.4 or below. ([rbenv][] is useful for switching between ruby versions.)
+
+```console
+$ gem install bundler
+```
+
+Then you need to install bundler dependencies.
+
+```console
+$ bundle install
+```
+
+Then hit the following command to build the site.
+
+```console
+$ npm run watch:docs
+```
+
+Then access `http://0.0.0.0:4567`.
+
+## Contributing your changes
+
+Add something about PRs here, indicate that PRs should not bump the version number & the build output files (`c3.js`, `c3.min.js`, `c3.css` & `c3.min.css`) should be excluded
+

+This automatically updates all the version numbers with a new one in the repository.
+
+Then hit the command:
+
+    npm run dist
+
+This builds the scripts and stylesheets. Then hit:
+
+    bmp -c
+
+This commits all the changes (including the built assets) and git-tags a new version (like v0.4.16):
+
+Then publish it to the npm registry (you need admin access to c3 module):
+
+    npm publish
+
+At this point, the new version is available through npm.
+
+Then push master and the tag to github:
+
+    git push origin master vX.Y.Z
+
+That's all.

+
+## Using the issue queue
+The [issue queue](https://github.com/c3js/c3/issues) is to be used for reporting defects and problems with C3.js, in addition to feature requests and ideas. It is **not** a catch-all support forum. **For general support enquiries, please use the [Google Group](https://groups.google.com/forum/#!forum/c3js) at https://groups.google.com/forum/#!forum/c3js.** All questions involving the interplay between C3.js and any other library (such as AngularJS) should be posted there first!
+
+Before reporting an issue, please do the following:
+
+1. [Search for existing issues](https://github.com/c3js/c3/issues) to ensure you're not posting a duplicate.
+
+1.  [Search the Google Group](https://groups.google.com/forum/#!forum/c3js) to ensure it hasn't been addressed there already.
+
+1. Create a JSFiddle or Plunkr highlighting the issue. Please don't include any unnecessary dependencies so we can isolate that the issue is in fact with C3. *Please be advised that custom CSS can modify C3.js output!*
+
+1. When posting the issue, please use a descriptive title and include the version of C3 (or, if cloning from Git, the commit hash — C3 is under active development and the master branch contains the latest dev commits!), along with any platform/browser/OS information that may be relevant.
+
+## Pull requests
+Pull requests are welcome, though please post an issue first to see whether such a change is desirable.
+If you choose to submit a pull request, please do not bump the version number unless asked to, and please include test cases for any new features. Squash all your commits as well, please.
+
+## Playground

+        %p In this guide, we are going to show you how to get started with C3.
+
+      %hr
+
+      %section
+        %h3
+          %a( href="#setup" ) 1. Setup
+        %p Download the latest version here:
+        %ul
+          %li <a href="https://github.com/c3js/c3/releases/latest" target="_blank">https://github.com/c3js/c3/releases/latest</a>
+        %p Installing by Bower/Component is also available with the name <span class="code">c3</span>.
+
+        %p Then, load the scripts and css:
+
+        .sourcecode.highlight
+          %pre
+            %code.html.xml
+              :preserve

+
+      %hr
+
+      %section
+        %h3
+          %a( href="#generate" ) 2. Generate Chart
+        %p C3 generates a chart by calling <span class="code">generate()</span> with the argument object, and an element including the chart will insert into the element specified as a selector in that argument as <span class="code">bindto</span>.
+
+        %p Prepare the element to bind the chart:
+        .sourcecode.highlight
+          %pre
+            %code.html.xml
+              :preserve
+                <span class="tag">&lt;<span class="title">div</span> <span class="attribute">id</span>=<span class="value">"chart"</span>&gt;&lt;/<span class="title">div</span>&gt;</span>
+
+        %p And, call <span class="code">generate()</span> with arguments:
+
+        .sourcecode.highlight
+          %pre
+            %code.javascript
+              :preserve
+                var chart = c3.generate({
+                    bindto: '#chart',
+                    data: {
+                      columns: [
+                        ['data1', 30, 200, 100, 400, 150, 250],
+                        ['data2', 50, 20, 10, 40, 15, 25]
+                      ]
+                    }
+                });
+
+        %p C3 supports the asynchronous module definition (AMD) API. If you use <a href="http://requirejs.org/" target="_blank">RequireJS</a>, you can load like this:
+
+        .sourcecode.highlight
+          %pre
+            %code.javascript
+              :preserve
+                require.config({
+                  baseUrl: '/js',
+                  paths: {
+                    d3: "http://d3js.org/d3.v5.min"
+                  }
+                });
+
+                require(["d3", "c3"], function(d3, c3) {
+                  c3.generate({
+                    ...
+                  });
+                });
+
+        %p Then, you will see the chart:
+
+        #chart2_1
+        %br
+
+        %p Data can be loaded as <a href="/samples/data_columned.html">columned data</a> / <a href="/samples/data_rowed.html">rowed data</a> / <a href="/samples/data_url.html">csv in URL</a>.
+        %p There are serveral options to customize the chart and you can see those here:
+        %ul
+          %li <a href="/examples.html">Examples</a>
+
+      %hr
+
+      %section
+        %h3
+          %a( href="#customize" ) 3. Customize Chart
+        %p The chart can be customize by giving some options when generating. We will introduce some of them here.
+
+        %h4 1. Additional Axis
+        %p Introduce additional axis for <span class="code">data2</span>. Add <span class="code">data.axes</span> and <span class="code">axis.y2.show</span> as follows:
+
+        .sourcecode.highlight
+          %pre
+            %code.javascript
+              :preserve
+                var chart = c3.generate({
+                    bindto: '#chart',
+                    data: {
+                      columns: [
+                        ['data1', 30, 200, 100, 400, 150, 250],
+                        ['data2', 50, 20, 10, 40, 15, 25]
+                      ],
+                      axes: {
+                        data2: 'y2' // ADD
+                      }
+                    },
+                    axis: {
+                      y2: {
+                        show: true // ADD
+                      }
+                    }
+                });
+
+        %p Then, the chart will be like this:
+
+        #chart3_1
+        %br
+
+        %h4 2. Show Axis Label
+        %p Show labels for each axis. Add <span class="code">axis.y.label</span> and <span class="code">axis.y2.label</span> as follows:
+
+        .sourcecode.highlight
+          %pre
+            %code.javascript
+              :preserve

+                    }
+                });
+
+        %p Then, the chart will be like this:
+
+        #chart3_2
+        %br
+
+        %h4 3. Change Chart Type
+        %p Show <span class="code">data2</span> as Bar chart. Add <span class="code">data.types</span> as follows:

+
+      %hr
+
+      %section
+        %h3
+          %a( href="#api" ) 4. Use APIs
+        %p By using APIs, you can update the chart after it's been rendered. We will introduce some of APIs here. APIs can be called through the object returned from <span class="code">generate()</span>.
+
+        %h4 1. Load Data
+        %p By using <span class="code">load()</span> API, you can load data and update the chart dynamically as follows:
+
+        .sourcecode.highlight
+          %pre
+            %code.javascript
+              :preserve
+                // var chart = c3.generate({ ... });
+
+                chart.load({
+                  columns: [
+                    ['data1', 300, 100, 250, 150, 300, 150, 500],
+                    ['data2', 100, 200, 150, 50, 100, 250]
+                  ]
+                });
+
+        %p If you push the button "Load" below, this code will run and the chart will be updated.
+
+        %button.small( onclick="example4_1();" ) Load
+
+        #chart4_1
+        %br
+
+        %h4 2. Unload Data
+        %p By using <span class="code">unload()</span> API, you can unload the data dynamically as follows:
+
+        .sourcecode.highlight
+          %pre
+            %code.javascript
+              :preserve
+                // var chart = c3.generate({ ... });
+
+                chart.unload({
+                    ids: ['data2', 'data3']
+                });
+
+        %p If you push the button "Unload" below, this code will run and the chart will be updated.
+
+        %button.small( onclick="example4_2();" ) Unload
+
+        #chart4_2
+        %br
+
+        %p Please use <span class="code">unload</span> param in <span class="code">load()</span> API if load and unload need to run simultaneously. Please see <a href="/samples/data_load.html">this example</a>.
+
+        %h4 3. Show/Hide Data
+        %p By using <span class="code">show()</span> and <span class="code">hide()</span> API, you can show/hide the data dynamically as follows:
+
+        .sourcecode.highlight
+          %pre
+            %code.javascript
+              :preserve
+                // var chart = c3.generate({ ... });
+
+                chart.hide(['data2', 'data3']);
+                chart.show(['data2', 'data3']);
+
+        %p If you push the button "Show" and "Hide" below, this code will run and the chart will be updated.
+
+        %button.small( onclick="example4_3_2();" ) Hide
+        %button.small( onclick="example4_3_1();" ) Show
+
+        #chart4_3
+        %br
+
+        %p The documentation about APIs is poor now, so please check the <a href="https://github.com/c3js/c3/issues?state=open">issues on github</a>. There might be some hints about what you want to do. (We will add the document soon)
+
+      %hr
+
+      %section
+        %h3
+          %a( href="#style" ) 5. Customize Style
+        %p C3 give some classes for each element when generating. So, you can change the style of the elements by using those classes.
+        %h4 1. Line style
+        %p The lines have <span class="code">c3-line-[id]</span> class, so this class can be used to define the style in css as follows:
+
+        .sourcecode.highlight
+          %pre
+            %code.css
+              :preserve
+                #chart .c3-line-data2 {
+                  stroke-width: 5px;
+                }
+
+        #chart5_1
+        %br
+
+        %p Please check the class for each element if you want to change the style. Web Inspector would be useful. (We will add the document for class definition soon)
+
+      %hr
+
+      %section
+        %h3
+          %a( href="#more" ) 6. And More..
+        %p Please check the <a href="/examples.html">examples</a> and the <a href="https://github.com/c3js/c3/issues?state=open">issues</a> on github for more information. Sorry for the poor documentation. We're working on now and please give me some time. Thank you.

+      %h3 Comfortable
+      %p
+        C3 makes it easy to generate D3-based charts by wrapping the code required to construct the entire chart. We don't need to write D3 code any more.
+    .medium-4.large-4.columns.supporticons
+      %h3 Customizable
+      %p
+        C3 gives some classes to each element when generating, so you can define a custom style by the class and it's possible to extend the structure directly by D3.
+
+    .medium-4.large-4.columns.supporticons
+      %h3 Controllable
+      %p
+        C3 provides a variety of APIs and callbacks to access the state of the chart. By using them, you can update the chart even after it's rendered.
+
+  %h3.text-center.sub

+  %h3 Browser Support
+  %p Because of the dependence on D3, C3 supports only modern browsers D3 supports. Please see <a href="https://github.com/mbostock/d3/wiki#browser--platform-support">the description in D3</a>.
+  %p Note: For IE9 and IE10, polyfill is required because c3 uses <span class="code">MutationObserver</span>, which is not supported in those versions. However, it's not required if charts always will be binded to the DOM specified by <span class="code">bindto</span> because <span class="code">MutationObserver</span> is not called in that case.
+
+  %h3 Dependency
+  %ul
+    %li <a href="https://github.com/mbostock/d3" target="_blank">D3.js</a> <span class="code">^4.12.0</span>
+  %p Note: If you need to use D3 v3.x, please use C3 <a href="https://unpkg.com/c3@0.4.22/c3.js">v0.4.22</a>, which is compatible with D3 v3.x.

+        <h1>C3 DataSet Reduction by Zoom Level</h1>
+        <h2>Hackathon May 2014</h2>
+        <h4>By Dan-el Khen</h4>
+        <p>Rendering graphs in the browser has many advantages, the downside is that takes a long time to render when having large datasets. </p>
+        <p>This feature allows you reduces the dataset according to your current zoom level.
+        It allows the developer to implement the reduction algorithm in a simple function that accepts an array of values, and returns a reduced single value.
+        The default reducer will take the first item, but avg/sum/first/last or any other algorithm is simple to implement.
+        </p>
+        <h3>Example</h3>
+        <p>
+            In the following example, we'll render 10K data points, each time we'll reduce those to about 100 items (depending on available size on your screen),
+            when zooming in, the resolution of the data will be better and more accurate. This would help in showing the big picture, even when the amount of data is bigger than the numbers of pixels on the screen.
+        </p>
+        <p>Click on the buttons or scroll with your mouse wheel inside the graph to zoom and/or pan.</p>
+        <pre id="status"></pre>

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"

+//	1. Enforce API surface and semantic compatibility with 1.9.x branch
+//	2. Improve the module's maintainability by reducing the storage
+//		paths to a single mechanism.
+//	3. Use the same single mechanism to support "private" and "user" data.
+//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
+//	5. Avoid exposing implementation details on user objects (eg. expando properties)
+//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

+ *   - The regex scope where the match was found: 'default' or 'class'.
+ *   - The flags used by the regex, including any flags in a leading mode modifier.
+ *   The handler function becomes part of the XRegExp construction process, so be careful not to
+ *   construct XRegExps within the function or you will trigger infinite recursion.
+ * @param {Object} [options] Options object with optional properties:
+ *   - `scope` {String} Scope where the token applies: 'default', 'class', or 'all'.
+ *   - `flag` {String} Single-character flag that triggers the token. This also registers the
+ *     flag, which prevents XRegExp from throwing an 'unknown flag' error when the flag is used.
+ *   - `optionalFlags` {String} Any custom flags checked for within the token `handler` that are
+ *     not required to trigger the token. This registers the flags, to prevent XRegExp from
+ *     throwing an 'unknown flag' error when any of the flags are used.
+ *   - `reparse` {Boolean} Whether the `handler` function's output should not be treated as
+ *     final, and instead be reparseable by other tokens (including the current token). Allows
+ *     token chaining or deferring.
+ *   - `leadChar` {String} Single character that occurs at the beginning of any successful match
+ *     of the token (not always applicable). This doesn't change the behavior of the token unless
+ *     you provide an erroneous value. However, providing it can increase the token's performance
+ *     since the token can be skipped at any positions where this character doesn't appear.
+ * @example
+ *
+ * // Basic usage: Add \a for the ALERT control code
+ * XRegExp.addToken(
+ *   /\\a/,
+ *   function() {return '\\x07';},
+ *   {scope: 'all'}
+ * );
+ * XRegExp('\\a[\\a-\\n]+').test('\x07\n\x07'); // -> true
+ *
+ * // Add the U (ungreedy) flag from PCRE and RE2, which reverses greedy and lazy quantifiers.
+ * // Since `scope` is not specified, it uses 'default' (i.e., transformations apply outside of
+ * // character classes only)
+ * XRegExp.addToken(
+ *   /([?*+]|{\d+(?:,\d*)?})(\??)/,
+ *   function(match) {return match[1] + (match[2] ? '' : '?');},

+## Filing an issue
+
+Before filing an issue, please [search the queue](https://github.com/c3js/c3/issues) to make sure it hasn't already been reported.
+
+If a bug, please include the following —
+
+1. What version of C3?
+1. What browsers have you confirmed it in?
+1. Can you isolate the issue by providing a jsFiddle demonstrating it in a minimalist capacity?
+
+Please *do not* ask for support using the issue queue. For support, please ask [on chat](https://gitter.im/c3js/c3) or [the mailing list](groups.google.com/forum/#!forum/c3js).
+
+## Setup
+ 1. **Clone the repo from GitHub**
+
+        git clone https://github.com/c3js/c3.git
+        cd c3
+
+ 2. **Acquire build dependencies.** Make sure you have [Node.js](http://nodejs.org/) installed on your workstation. This is only needed to _build_ C3 from sources. C3 itself has no dependency on Node.js once it is built. Now run:
+
+        npm install -g grunt-cli
+        npm install
+
+    The first `npm` command sets up the popular [Grunt](http://gruntjs.com/) build tool. You might need to run this command with `sudo` if you're on Linux or Mac OS X, or in an Administrator command prompt on Windows. The second `npm` command fetches the remaining build dependencies.
+
+## Building C3 from sources
+    npm run build
+
+
+## Distribution
+    npm run dist
+
+Now you'll find the built files in `c3.js`, `c3.min.js`, `c3.css` & `c3.min.css`.
+
+## Running the tests
+    npm run test
+
+This command will automatically run the specification suite and report its results.
+
+If you want to see specs running live in browser (e.g., for debugging), simply open `http://localhost:9876/` in your browser when phantomjs starts.
+
+## Building the document site (c3js.org)
+
+First you need ruby and [bundler][] to build the documentation site.
+
+**Note:** Currently the site doesn't build with ruby 2.5.x, so you need ruby 2.4.4 or below. ([rbenv][] is useful for switching between ruby versions.)
+
+```console
+$ gem install bundler
+```
+
+Then you need to install bundler dependencies.
+
+```console
+$ bundle install
+```
+
+Then hit the following command to build the site.
+
+```console
+$ npm run watch:docs
+```
+
+Then access `http://0.0.0.0:4567`.
+
+## Contributing your changes
+
+Add something about PRs here, indicate that PRs should not bump the version number & the build output files (`c3.js`, `c3.min.js`, `c3.css` & `c3.min.css`) should be excluded
+

+# Release process
+
+If you don't have `bmp` command installed, first install `bmp` ruby gem:
+
+    gem install bmp
+
+When master is ready for the next release, hit the command:
+
+    bmp -p
+
+This automatically updates all the version numbers with a new one in the repository.
+
+Then hit the command:
+
+    npm run dist
+
+This builds the scripts and stylesheets. Then hit:
+
+    bmp -c
+
+This commits all the changes (including the built assets) and git-tags a new version (like v0.4.16):
+
+Then publish it to the npm registry (you need admin access to c3 module):
+
+    npm publish
+
+At this point, the new version is available through npm.
+
+Then push master and the tag to github:
+
+    git push origin master vX.Y.Z
+
+That's all.

+## Google Group
+For general C3.js-related discussion, please visit our [Google Group at https://groups.google.com/forum/#!forum/c3js](https://groups.google.com/forum/#!forum/c3js).
+
+## Gitter
+[![Join the chat at https://gitter.im/c3js/c3](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/c3js/c3?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
+
+## Using the issue queue
+The [issue queue](https://github.com/c3js/c3/issues) is to be used for reporting defects and problems with C3.js, in addition to feature requests and ideas. It is **not** a catch-all support forum. **For general support enquiries, please use the [Google Group](https://groups.google.com/forum/#!forum/c3js) at https://groups.google.com/forum/#!forum/c3js.** All questions involving the interplay between C3.js and any other library (such as AngularJS) should be posted there first!
+
+Before reporting an issue, please do the following:
+
+1. [Search for existing issues](https://github.com/c3js/c3/issues) to ensure you're not posting a duplicate.
+
+1.  [Search the Google Group](https://groups.google.com/forum/#!forum/c3js) to ensure it hasn't been addressed there already.
+
+1. Create a JSFiddle or Plunkr highlighting the issue. Please don't include any unnecessary dependencies so we can isolate that the issue is in fact with C3. *Please be advised that custom CSS can modify C3.js output!*
+
+1. When posting the issue, please use a descriptive title and include the version of C3 (or, if cloning from Git, the commit hash — C3 is under active development and the master branch contains the latest dev commits!), along with any platform/browser/OS information that may be relevant.
+
+## Pull requests
+Pull requests are welcome, though please post an issue first to see whether such a change is desirable.
+If you choose to submit a pull request, please do not bump the version number unless asked to, and please include test cases for any new features. Squash all your commits as well, please.
+
+## Playground
+Please fork this fiddle:

+          %a( href="#generate" ) 2. Generate Chart
+        %p C3 generates a chart by calling <span class="code">generate()</span> with the argument object, and an element including the chart will insert into the element specified as a selector in that argument as <span class="code">bindto</span>.
+
+        %p Prepare the element to bind the chart:
+        .sourcecode.highlight
+          %pre
+            %code.html.xml
+              :preserve

+
+        %p And, call <span class="code">generate()</span> with arguments:
+
+        .sourcecode.highlight
+          %pre
+            %code.javascript
+              :preserve
+                var chart = c3.generate({

+                    data: {
+                      columns: [
+                        ['data1', 30, 200, 100, 400, 150, 250],
+                        ['data2', 50, 20, 10, 40, 15, 25]
+                      ]
+                    }
+                });
+
+        %p C3 supports the asynchronous module definition (AMD) API. If you use <a href="http://requirejs.org/" target="_blank">RequireJS</a>, you can load like this:
+
+        .sourcecode.highlight
+          %pre
+            %code.javascript
+              :preserve

+                    ...
+                  });
+                });
+
+        %p Then, you will see the chart:
+
+        #chart2_1
+        %br
+
+        %p Data can be loaded as <a href="/samples/data_columned.html">columned data</a> / <a href="/samples/data_rowed.html">rowed data</a> / <a href="/samples/data_url.html">csv in URL</a>.

+        %p The chart can be customize by giving some options when generating. We will introduce some of them here.
+
+        %h4 1. Additional Axis
+        %p Introduce additional axis for <span class="code">data2</span>. Add <span class="code">data.axes</span> and <span class="code">axis.y2.show</span> as follows:
+
+        .sourcecode.highlight
+          %pre
+            %code.javascript
+              :preserve

+                        ['data1', 30, 200, 100, 400, 150, 250],
+                        ['data2', 50, 20, 10, 40, 15, 25]
+                      ],
+                      axes: {
+                        data2: 'y2' // ADD
+                      }
+                    },
+                    axis: {

+                    }
+                });
+
+        %p Then, the chart will be like this:
+
+        #chart3_1
+        %br
+
+        %h4 2. Show Axis Label
+        %p Show labels for each axis. Add <span class="code">axis.y.label</span> and <span class="code">axis.y2.label</span> as follows:
+
+        .sourcecode.highlight
+          %pre
+            %code.javascript
+              :preserve

+                        ['data2', 50, 20, 10, 40, 15, 25]
+                      ],
+                      axes: {
+                        data2: 'y2'
+                      }

+                });
+
+        %p Then, the chart will be like this:
+
+        #chart3_2
+        %br
+
+        %h4 3. Change Chart Type
+        %p Show <span class="code">data2</span> as Bar chart. Add <span class="code">data.types</span> as follows:
+
+        .sourcecode.highlight
+          %pre
+            %code.javascript
+              :preserve

+                    }
+                });
+

+        %br
+
+        %h4 4. Format values
+        %p Format the values of each data. Add <span class="code">axis.y.tick.format</span> as follows:

+
+      %section
+        %h3
+          %a( href="#api" ) 4. Use APIs
+        %p By using APIs, you can update the chart after it's been rendered. We will introduce some of APIs here. APIs can be called through the object returned from <span class="code">generate()</span>.
+
+        %h4 1. Load Data
+        %p By using <span class="code">load()</span> API, you can load data and update the chart dynamically as follows:
+
+        .sourcecode.highlight
+          %pre
+            %code.javascript
+              :preserve
+                // var chart = c3.generate({ ... });
+
+                chart.load({
+                  columns: [
+                    ['data1', 300, 100, 250, 150, 300, 150, 500],
+                    ['data2', 100, 200, 150, 50, 100, 250]
+                  ]
+                });
+
+        %p If you push the button "Load" below, this code will run and the chart will be updated.
+
+        %button.small( onclick="example4_1();" ) Load
+
+        #chart4_1
+        %br
+
+        %h4 2. Unload Data
+        %p By using <span class="code">unload()</span> API, you can unload the data dynamically as follows:
+
+        .sourcecode.highlight
+          %pre
+            %code.javascript
+              :preserve
+                // var chart = c3.generate({ ... });
+
+                chart.unload({
+                    ids: ['data2', 'data3']
+                });
+
+        %p If you push the button "Unload" below, this code will run and the chart will be updated.
+
+        %button.small( onclick="example4_2();" ) Unload
+
+        #chart4_2
+        %br
+
+        %p Please use <span class="code">unload</span> param in <span class="code">load()</span> API if load and unload need to run simultaneously. Please see <a href="/samples/data_load.html">this example</a>.
+
+        %h4 3. Show/Hide Data
+        %p By using <span class="code">show()</span> and <span class="code">hide()</span> API, you can show/hide the data dynamically as follows:
+
+        .sourcecode.highlight
+          %pre
+            %code.javascript
+              :preserve
+                // var chart = c3.generate({ ... });
+
+                chart.hide(['data2', 'data3']);
+                chart.show(['data2', 'data3']);
+
+        %p If you push the button "Show" and "Hide" below, this code will run and the chart will be updated.
+
+        %button.small( onclick="example4_3_2();" ) Hide
+        %button.small( onclick="example4_3_1();" ) Show
+
+        #chart4_3
+        %br
+
+        %p The documentation about APIs is poor now, so please check the <a href="https://github.com/c3js/c3/issues?state=open">issues on github</a>. There might be some hints about what you want to do. (We will add the document soon)
+
+      %hr
+
+      %section
+        %h3
+          %a( href="#style" ) 5. Customize Style
+        %p C3 give some classes for each element when generating. So, you can change the style of the elements by using those classes.
+        %h4 1. Line style
+        %p The lines have <span class="code">c3-line-[id]</span> class, so this class can be used to define the style in css as follows:
+
+        .sourcecode.highlight
+          %pre
+            %code.css
+              :preserve
+                #chart .c3-line-data2 {
+                  stroke-width: 5px;
+                }
+
+        #chart5_1
+        %br
+
+        %p Please check the class for each element if you want to change the style. Web Inspector would be useful. (We will add the document for class definition soon)
+
+      %hr
+
+      %section
+        %h3
+          %a( href="#more" ) 6. And More..
+        %p Please check the <a href="/examples.html">examples</a> and the <a href="https://github.com/c3js/c3/issues?state=open">issues</a> on github for more information. Sorry for the poor documentation. We're working on now and please give me some time. Thank you.

+      %h3 Comfortable
+      %p
+        C3 makes it easy to generate D3-based charts by wrapping the code required to construct the entire chart. We don't need to write D3 code any more.
+    .medium-4.large-4.columns.supporticons
+      %h3 Customizable
+      %p
+        C3 gives some classes to each element when generating, so you can define a custom style by the class and it's possible to extend the structure directly by D3.
+
+    .medium-4.large-4.columns.supporticons
+      %h3 Controllable
+      %p
+        C3 provides a variety of APIs and callbacks to access the state of the chart. By using them, you can update the chart even after it's rendered.
+
+  %h3.text-center.sub
+    C3 enables deeper integration of charts into your application.

+  %h3 Browser Support
+  %p Because of the dependence on D3, C3 supports only modern browsers D3 supports. Please see <a href="https://github.com/mbostock/d3/wiki#browser--platform-support">the description in D3</a>.
+  %p Note: For IE9 and IE10, polyfill is required because c3 uses <span class="code">MutationObserver</span>, which is not supported in those versions. However, it's not required if charts always will be binded to the DOM specified by <span class="code">bindto</span> because <span class="code">MutationObserver</span> is not called in that case.
+
+  %h3 Dependency
+  %ul
+    %li <a href="https://github.com/mbostock/d3" target="_blank">D3.js</a> <span class="code">^4.12.0</span>
+  %p Note: If you need to use D3 v3.x, please use C3 <a href="https://unpkg.com/c3@0.4.22/c3.js">v0.4.22</a>, which is compatible with D3 v3.x.

+        <h1>C3 DataSet Reduction by Zoom Level</h1>
+        <h2>Hackathon May 2014</h2>
+        <h4>By Dan-el Khen</h4>
+        <p>Rendering graphs in the browser has many advantages, the downside is that takes a long time to render when having large datasets. </p>
+        <p>This feature allows you reduces the dataset according to your current zoom level.
+        It allows the developer to implement the reduction algorithm in a simple function that accepts an array of values, and returns a reduced single value.
+        The default reducer will take the first item, but avg/sum/first/last or any other algorithm is simple to implement.
+        </p>
+        <h3>Example</h3>
+        <p>
+            In the following example, we'll render 10K data points, each time we'll reduce those to about 100 items (depending on available size on your screen),
+            when zooming in, the resolution of the data will be better and more accurate. This would help in showing the big picture, even when the amount of data is bigger than the numbers of pixels on the screen.
+        </p>
+        <p>Click on the buttons or scroll with your mouse wheel inside the graph to zoom and/or pan.</p>
+        <pre id="status"></pre>
