Creating graphs on web pages used to be a somewhat developer and processor intensive endeavor. With the canvas tag now supported by Firefox 1.5, Safari, and Opera, it’s now possible to create a web developer to create nice looking graphs about as easily as text.

CanvasGraph is a “small simple javascript library that allows you to conveniently plot simple line, bar and pie charts using the new HTML Canvas Tag.”

The author uses the library to good effect on the Liquidx stats page.
