Choropleth map with proportional symbols

http://geographyfieldwork.com/DataPresentationMappingTechniques.htm
This is a choropleth map with proportional symbols.  The shades of purple represent classifications of population density.  In this example the classes are divided by set intervals (not natural breaks or by standard deviation).  The pie charts represent the differences in land use within the region.  By having two sets of symbols on the map, it is able to communicate more information about the area.
