Hi,

Just an FYI that projects downstream from Bokeh (such as Dask and Holoviews) have begun contributing minimal Bokeh-specific test suites to the Bokeh project to run during our Continuous Integration testing. Certainly we intend not to make any breaking changes at this point, but the "downstream" tests allow us to be extra careful not to disturb any downstream projects. (These tests are currently advisory-only in order to avoid too-tight coupling between project state, but we observe the results regularly).

I'd like to invite you to contribute a test suite for Chartify. The relevant files are here:

https://github.com/bokeh/bokeh/blob/master/scripts/ci/install.downstream
https://github.com/bokeh/bokeh/blob/master/scripts/ci/test.downstream

I'm happy to answer any questions or assist however I can.
