v0.10.0

New! ✨

• New TripsLayer for animating moving objects, which integrates with MovingPandas. See the Air Traffic Control example and the MovingPandas integration example.
• New ColumnLayer for rendering extruded cylinders. See the new ColumnLayer example.
• Removed required dependencies! geopandas, pandas, shapely, pyarrow, matplotlib, and palettable are now optional dependencies. Lonboard will still work out of the box with them, but they aren't required to use Lonboard. This gives Lonboard a smaller footprint and makes it easier to use in environments such as Pyodide.
• You can now draw bounding boxes on the map. This is exposed as the selected_bounds attribute on the Map object, stored as a two-dimensional bounding box (minx, miny, maxx, maxy).
• Improved documentation
  • How to use Lonboard in pyodide, a Python environment that is fully running in your browser.
  • Add linked maps example by @ATL2001 in #655
  • Add troubleshooting doc by @kylebarron in #654
  • Add longraph to showcase by @kylebarron in #595
• New Map.add_layer method for easily adding more layer(s) to an existing Map instance.
• Add highlight_color to change the color of auto_highlight by @kylebarron in #666
• Use deterministic colors in viz by @kylebarron in #621
• Categorical data filtering. The DataFilterExtension now has a filter_categories attribute that lets you filter categorical data on the map. by @kylebarron in #609

Breaking Changes 🔨

• The tooltip shown on hover was replaced with a side panel. You now must click on a geometry to view its attributes. By @vgeorge in #636

Fixes 🐛

• We've switched from storing list objects to storing tuple objects (e.g. the list of layers in a Map). The immutability of the tuple ensures that a any changes in the sequence of layers will be propagated to the frontend.Fixed in #620
• A class of bugs was fixed when using Arrow input, where the chunking structure of the main table did not match the chunking of accessors. Fixed in #644
• Fix reading from DuckDB with only geometry column by @kylebarron in #625
• Fix attribution by @vgeorge in #561
