Tufte calls it the fallacy of the dollar bill -- using area to depict a one-dimensional value. Still a haunting graphic when viewed in diameters. I live in Michigan so I am acutely aware of our leadership role in unemployment. The first comment hits my complaint.

Of course LA, Chicago, and NYC lost more jobs than Detroit, they are several times larger (none however are approaching the 25% unemployment of Detroit). This figure doesn't really given anyone an idea of where people are losing jobs, so much as where most people live.

If you take the legend as an example, the diameter of the 10,000 person size circle is maybe 1/8th (conservatively) the diameter of the 100,000 person size circle. If that is the case, the actual area of the 100,000 person circle is 64 times as large as the 10,000 person circle, far overstating the difference in population sizes. To accurately show the difference of a factor of 10, the diameter of a should be 3.162 (the square root of 10) times larger than the smaller circle.
