You Ready To Go Gung HO? A Hotshot Challenge

One thing we haven't dealt with is color. Our heat map is built by dots of a uniform blue. As they're semi-opaque, they get darker as more dots appear in a condensed area, but with enough data, we should aim to change the color, going through red, yellow, and right up to white for the most-clicked areas. See if you can add this functionality yourself to really top the project off.
