This article explains why these graphs are useful, how to interpret them and instructions for how to draw your own.

P roportional symbols can be any shape, but are usually circles or squares. The size of these shapes will depend on the data they represent — the larger the value, the bigger the shape and vice versa. Once the size of the shape has been determined they are usually located on a map, making it easy to compare data from different places.
