Dot Distribution

 I created this map using ArcGIS

This is a Dot Distribution map of Maricopa County, Arizona that shows voting districts, voting age population, and schools in the year 2000.  The dots represent census block voters; the size of the dot conveys the amount of voters in the area.  This type of map could be used as a political agenda, for redistricting, or even gerrymandering.  I downloaded the census block polygons, voting districts, and demographics from ERSI, Inc. 2000 and also from my GIS Tutorial Updated for ArcGIS 9.3.
