This is an interesting interactive map that is using Google Maps API to show the various expenses within states for public schools. This map is just one of a series that you can find on the website. Its interesting since it is a very simple map using just layers over a regular Google Map. However, by using Google Maps it allows users to zoom in as much as they would like (not that it's necessary to see colors) but it gives a good feel for basic interactive maps.
