Zoomable Treemap in Bokeh

Question

I was wondering if anyone had any links to work for a zoomable treemap in Bokeh. Similar to the Mike Bostock example: https://bost.ocks.org/mike/treemap/

In particular: there doesn't seem to be (as yet) a treemap layout in Bokeh, perhaps this would be the first place to start? Then I would assume that some form of animation would need to be done to flow from one tree hierarchy to the next.

Answer 1

You could do something like this in Bokeh, but you would need to compute the space-packing/rectangle positions manually, there is nothing built in to do this.

Additionally, as of Bokeh 0.13.0, "smooth animations" is still an open issue on GitHub, so the transitions would be instantaneous, not "zoomy".

If you'd like to have something considered as a new feature (especially if you can help contribute), the best thing is to make a GitHub issue to discuss it.
