One can quibble about the best way to display county-level unemployment data on a map, since a small, populous county gets much less visual weight than a large, sparsely populated one. Even so, I think we can agree that this animated map by LaToya Egwuekwe is pretty cool. It says it shows the unemployment rate by county, as a function of time, but anyone with even the slightest knowledge of what happens during a zombie attack will recognize it for what it is.
Nebraska never looked so appealing: anatomy of a zombie attack. Oops, I mean a recession.
