''' Create a simple genomics data stats dashboard.
Choose pages to show in the drop down widgets, and make selections
on the plots to update the summary and histograms accordingly.
.. note::
Use the ``bokeh serve`` command to run the example by executing:
bokeh serve --show --port 5109 /Users/xli677/Dropbox (Uni of Auckland)/xli677/Projects/MyTardis/Visualisation_with_Bokeh/test.py
at your command prompt. Then navigate to the URL
http://localhost:5006/stocks
