Bivariate choropleth maps:
A bivariate map displays two variables on a single map by combining two different sets of graphic symbols or colors. Bivariate mapping is an important technique in cartography. Given a set of geographic features, a bivariate map displays two variables on a single map by combining two different sets of graphic symbols. It is a variation of simple choropleth map that portrays two separate phenomena simultaneously. The main objective of a bivariate map is to find a simple method for accurately and graphically illustrating the relationship between two spatially distributed variables. A bivariate map has potential to reveal relationships between variables more effectively than a side-by-side comparison of the corresponding univariate maps
