CanvasGraph - js graphic utils

Canvas. Canvas! Canvas? CANVAS!
I've been going canvas crazy lately. With good reason I might add.
Anyway, I tend to run across new cool stuff using canvas, and this one is very high on the cool-o-meter. It's a simple js library to create bar graphs and pie charts and such using canvas and mochikit. Check it out if you have Safari 2.0, Opera 9, or Mozilla 1.5.
