Pie Chart on top of choropleth map

Hi all,

I am trying to add Pie chart on top of a choropleth map. I see there has been a post on this topic, Plotting pie charts on a map, but there was no good solution 2 years ago.

I wonder if anyone has a good solution to this problem. I have been working on this for a week, but have not been able to find a good solution. Any suggestion would be greatly appreciated.


Can you use Dash? With Dash I think you can use dcc.Tooltip to show another graph when hovering points on scatter_geo. You can refer it here:

Thank you so much!
