Range Graded Proportional Circle Map


The Range Graded Proportional Circle Map also uses circles to describe information. Circles are used because it is easier for the reader to understand. Generally, the Range Graded Proportional Circle Map has information that does not change often. It should also be noted, that one of the big factors for this type of map is that the information is broken into groups and each circle size describes a different group.
