Here is a really important map riddled with little Chernoff-like faces.
It’s just such a fun data set, I can’t help myself.
Here is a bit of a how-to, if you are Chernoff-inclined.
In the meantime, here’s a close-up of those faces (drawn in Illustrator)!
Cheers! John

Two criticisms:
1. Very few people have an intimate understanding of US geography by county so they will immediately be lost.
2. Since the symbols are so densely placed, you can’t tell the differences between the faces.
I would love to see this again with only cities > X population or go by states and see if that is more readable.

I’ll get right on that, Matthew!
