Continuously variable proportional circle map

 

I created this map using ArcMap

This is a continuously variable proportional circle map of Hispanic people in California normalized to the population in the year 2000.  These maps show each symbol proportional to the data such as shown above.  The larger circles indicate 1% Hispanic citizens in the total population of California, so all of the circles totaled up should equal the total percent of Hispanic citizens relative to the overall population.  I downloaded the data from the ArcGIS tutorial, clipped out the cities, and created six classes to distinguish different amounts of Hispanic populations.
