Choropleth Map


Choropleth Maps are thematic maps that use shading or patterns in proportion to the represented data. The darker colors are perceived as being of higher magnitude. The drawbacks with choropleth maps is that smaller areas may not have much relation to the data so the contrast wont be be great. So , larger areas are needed to be used in order to show the visual impact needed, making the information somewhat misleading.
