I am trying to use GeoRegionValuePlot[], to make a heat map for US counties, given a certain value. When I attempt to plot a small number of plots, it runs fine. When I try to do the 240 or so counties that I want to illustrate, the kernel hangs and it finally, after being unresponsive for a LONG time, returns an internet connectivity issue statement.
Thanks for the quick response. I pasted your code into a notebook on my Macbook and like my code, it stalls and never produces the map. See the screen grab of where it is stuck.
