Continuously variable proportional circle map

http://geochristian.com/category/politics/

Continuously variable proportional circle maps are much like proportional circle maps but are more accurate.  The reason this type of map is more accurate is because its values are absolute and have the ability to change.  Instead of quantitized sizes each size is different.  The map above is a good example of a continuously variable proportional circle map because each circle represents its own value therefore is a certain size.
