Detailed Heatmaps (States & Cities)

It would be valuable to enhance the global country heatmap with more detailed country views.

Since region and city data is already available, a country view that shows individual states with colors that reflect their traffic volume would make the data much easier to understand. It would also be useful to include a country view that marks cities with dots at their locations. The intensity or size of each dot could indicate how much traffic comes from that city.
