Quite the eye-catching chart this:
The original accompanied this article in the Wall Street Journal about avian flu outbreaks in the U.S.
The point of the chart appears to be the peak in the flu season around May. The overlapping bubbles were probably used for drama.
A column chart, with appropriate colors, attains much of the drama but retains the ability to read the data.
