I frequently receive Covid infection data at the level of census tract. I have downloaded the TIGER directory for my state from Census.gov which contains all the data that one would need to connect a GEOID to a polygon to display the particular census tract area as a location on a map.
It's unclear to me from the Mathematica documentation how I would go about instructing Mathematica get the pieces from the Tiger file to display the census tract on a map.
I think a few examples using Mathematica's GIS primitives at least would get me started.
