What is a Heatmap?
Wikipediadefines a heat map as a graphical representation of data where the individual values contained in a matrix are represented as colors. In WP Google Maps v6 the colors represent the density of “Markers” on the Map within an area drawn in the Map Editor. Since the radius of the heatmap area is fixed regardless of zoom level, it’s useful for showing a lot of things that gradually separate as you zoom in.
