The current state of antialiased lines with various reductions was summaries in PR #1146. Test code and images are reproduced here: ```python import datashader as ds import datashader.transfer_functions as tf...

There should be an explicit section or page of the project documentation to explain antialiased lines. There is some mention of this in the timeseries page of the user guide.

Work in progress to update the census example environment to use the latest `datashader`, `bokeh`, `panel`, etc. Initially using `datashader` dev release `0.14.5a` from `pyviz/label/dev` channel, and other packages from...

Problems initializing Models using BokehJS without Python
