Univariate Choropleth Maps



Univariate choropleth maps are basic choropleth maps that present only one set of data, unlike bivariate choropleth maps that present two sets of unrelated data. This particular choropleth map presents the presidential vote to the electoral votes in percent of mean. The map is divided into 5 intervals of percentages. This data shows that votes per ballot are not equally distributed. This map is taken from http://www.cartisan.com/map_resources/map_types/images/choropleth.jpg.
