Bubble Map

Bubble Maps (or proportional symbol maps) are a class of maps that use the visual variable of size to represent differences in the magnitude of a discrete, abruptly changing phenomenon, e.g. counts of people.
Bubble Maps are very similar to Bubble Chart, but instead of a coordinate grid a geographic map is used.
