This should do it:
https://github.com/ghomem/coviz/commit/70036c68e0c241d66585c770f811958981e3eb3a
but in reality, even though it seems that I am updating the data_source, it does not make the plot change. Does not seem to be much faster either.
This actually works:
https://github.com/ghomem/coviz/pull/3/files
but it ain't faster than what I originally had. Any ideas? Thanks in advance :-)
Found a way to make it work very fast:
https://github.com/ghomem/coviz/pull/4/
However the tooltips are not updating (they keep the old values).
Well, after some hair pulling I managed to solve this. The details are here:

final PR:
Hi,
I am using plot_bokeh to render a plot based on a GeoDataFrame counties as rows, to which an 'incidence' column has been added:
https://coviz.io/#section3
and it works great.
This incidence column is updated as a function of a slider change.
I have a difficulty concerning the method of updating the plot everytime the slider is changed: because the datasource is not accessible I didn't find a way to update the plot other than generating a new one and inserting it into the layout. This works, but it is rather CPU consuming and causes a ~5 seconds lag.
Any suggestion?
