Continuously Variable Circle Map



Continuously Variable Proportional Circle maps, as the name suggests, uses circles to display information to create point data. These circles are proportional to the measured variables.  The map above uses spheres to represent the Mexican population of western United States in 1990 based on information from the U.S. census.
