Nominal area choropleth map

Nominal area choropleth maps generally use data that is nominal or non quantitative. These maps are good when you just want to display a general overview. For example in the map below we see which states each candidate won in the 2000 election. It doesn't show how many people voted for each candidate, rather it just simply shows which candidate won which state.
