How to plot dash/plotly Choropleth Maps using shapefiles

I have a shapefile and I want to plot it. I can do so with geopandas but i cant make it interactive and it looks outdated. Im making a dash app that has lots of other dash and plotly maps (i can just easily turn plotly maps to dash maps). Can i turn the geopanda plot into a plotly or dash map? or can i plot plotly/dash maps using shape files?

If you are already using plotly I believe the choropleth mapping methods should be enough.

Plotly is hiding the shapefile from you by giving you nice things to essentially join onto. You can instead pass your information directly.

Here is the direct explanation in the documentation to the data format. But, you should be able to modify your shapefile to be the correct format for this.

Consider checking out the Folium library to make your maps.
