Choropleth Maps

A choropleth map is one that has a certain theme to it and is shown by different colors. In this map to the left the theme can be seen in the title. It is the U.S. divorce rates by county. There is a key in the bottom left corner of the map. This map conveys so much data because it breaks down every county in the United States. It can be hard to read and see each county but it is easier to convey data when using colors in my opinion. Choropleth maps are my favorite.
