Proportional Symbols
In this exercise, you will create three different proportional circle maps showing gasoline consumption by state in 2004.
Each map will emply a different method for determining circle sizes. The methods will consist of an absolute scaling method, a psychological scaling method and a range-graded method. You will be determining circle sizes for each state.
-For the absolute scaling method, use the square-root method;
-For the psychological scaling method, use Flannery's method;
-For the range graded method, use natural breaks.
You can produce your maps in black & white, or in color; that is up to you. Again, you should adhere to principles learned in previous labs. For this lab, this includes balance and layout, figrue-ground contrast, type placement, titles, legends, scales, and other marginal information.
