First of all, congratulation for your development on Bokeh. I recently started to use it, it is a great tool.
My joob is to include analytical graphs inside a Flask app, and Bokeh seems a great option. I will really appreciate if you recommend me some advance examples or tutorials that cover the topic of using 2 or more widgets, multiple selection, to filter a large data set and interactively change the final plot, specially using CustomJS Callbacks, because it seems more easy to include the final script on some html file. The Gallery in the standalone section does not include this type of use.
Thank you in advance for your kind help.
