I'd like to create a zoomable world map where countries/territories are color-coded. This is a pretty standard request and Carto has a nice example.
However, in standard maps like this, small countries are practically invisible unless you zoom in, so I'd like to highlight them the way Wikipedia often does:
Larger version here, and note that small countries have a circle superimposed on top.
Is there an existing library/package/... that can do this in a popular tool like Carto? Bonus points if the circles go away when you zoom in close enough. The closest I could find with some searching was Using 'Style by Value' with Point Geometries, but this uses dots instead of country polygons, which is not what I'm looking to do.
