I wonder what the best way is to group populations from neighboring counties.
The east coast has a much higher density of small counties, giving the NY area a look very different from that around LA.

Compare the Houston and Dallas metro areas - Houston has a very distinct large bubble, while Dallas has more overlapping smaller bubbles which make it look smaller, even though it contains more people.
