Classed Choropleth Maps

A classed chloropleth map uses colors to discriminate between the data of a selected class. A mapper will decide on how many classes he or she wants to represent based on a number of things such as quantiles and display those classes using different shades of a color to represent the intesnity of the data. Generally greater amounts of data are represented using bolder shades of a color while smaller values are represented by lighter shades. The map below shows the number of deaths per 1,000 live births for Australia.
