How can I make a mosaic/merimekko chart in a Bokeh dashboard?

I am creating a dashboard using Bokeh and I want to create a Merimekko, or alternatively, a mosaic chart to use in the dashboard. I tried looking around but it doesn’t look like Bokeh can make these. Is there any other way I can make and incorporate this chart on my dashboard? Any specific libraries that could be used?

They are stacked, range-filling, variable-width bar charts. Bokeh can draw that sort of chart with vbar or vbar_stack without any question. ^[1] But you will need to compute the positions and widths and heights of the bars yourself. And as far as I know, that is more or less also the case with all of the other common Python plotting libraries. I am not aware that any of them have this “built in” as single function you could call, or anything like that.
