We’ve developed a PHP Class for drawing a CSS graph. The CSS and XHTML code for this class was originally developed by Meyerweb, we just took it and wrapped a PHP class around it. This class is also hosted over at phpclasses.org if you prefer to get your stuff on that site, but keep in mind that the CodeVault link below will always contain the latest version.
