Geo-visualization by Cartograms

Cartograms are types of maps in which  statistical information is represented relative to the area of the spatial unit to which the statistical information belongs. Cartograms can be used to create more insight on the spatial distribution of a particular variable with respect to the different spatial areas under consideration.

During the Cartography and Geo-visualization course,  cartograms were used to represent various variables in Kenya. For instance, the maps below show the spatial distribution of poverty in Kenya and accessibility to electricity within the country.
