SVG Chart Demo is currently OFFLINE Until it is back up you can check out the development code
SVG is now supported in Modern browsers. That means on Firefox 2.x and 3.x, Camino 1.x, Safari 3.x and Opera 9.x. Not Microsoft IE. SVG is a great addition to the web but it is an open standard and of little interest to Microsoft. SVG is viewable in IE with the Adobe SVG Viewer. Unfortunately, the closed source competing standard to SVG is Flash. Macromedia, the creators of flash, have been bought by by Adobe. Expect Adobe and Microsoft to continue to drag their heels to prevent wider acceptance of SVG in favor of proprietary offerings by these two monopoly players.
Browser problems: Again, Microsoft IE is the real problem. there are efforts underway to get Google canvas support through VML. I just wish people would quit using IE. Then Microsoft might care about programming to standards rather than forcing the world ... I'll save that rant for later.
