I didn’t want post a GitHub issue for this (but happy to if you want). I am a beginner developer but I use Bokeh a lot and have come to rely on it.
One thing I noticed is that the High-Level Charts page in the user guide makes no reference to Chord, Donut, HeatMap, Horizon, or Time Series charts. Though, these are very well documented in the reference pages.
Would you accept a pull request that covers these charts in the User Guide? Even just a reference to them and links to their entries in the reference section would be really helpful.
For myself, I spent an hour or so plotting wedges in order to get a pie type chart along with other Bokeh charts on my page before I found Donut which was perfect for my needs.
I am pretty sure I can follow how the rst docs work and how the chart images become embedded so should be straightforward if you al think the contribution would be helpful.
