HOW states are visualizing their cases is actually pretty interesting. Here's OH, with gradients at logical places (50, 100, 500, 1000, 2000). (The darkest, btw, is Marion prison, where the state is testing everyone.)

MI counts are arbitrary cut-offs that at least show how the virus exists at different concentrations across the state (tho doesn't break out Detroit City).

Here's GA's map, with cutoffs that make it look like most of the state is unaffected. Open up! this map says.

Of course that hides what's really going on in GA, which is that there's a really big cluster in rural SE GA. Randolph County has 2124 cases/100K people.

This is a heavily black area w/a devastating number of cases for its population.

In other states, the big surge in cases are prisoners. https://twitter.com/jeremychrysler/status/1252320702994231298

Here's AZ's cases per county versus AZ's cases per 100,000, which shows how devastating the Navajo cluster is.
