proportional circle map


A proportional circle map is a map that gives information on different data such as population size or density by using different size circles. This is a map of Europe from 2004 and shows how many Internet users there are in certain areas of Europe. The bigger the circles are the more Internet users there are in that area and the smaller the circle, the less there are in that area.

choropleth map


A choropleth map is a thematic map that is shaded to a certain degree of darkness relative to the density of the information that it is trying to present. For example, this map of Florida shows the percent of Hispanics per county. The darkest green is 35.7 to 57.3 percent and correlates to the map as Dade and a few other South Florida Counties. The lightest shade is 1.5 to 3.9 percent and most of the Northern and some central counties are in this range.
