"SVG Web is a JavaScript library which provides SVG support on many browsers, including Internet Explorer, Firefox, and Safari. Using the library plus native SVG support you can instantly target ~95% of the existing installed web base.

Once dropped in you get partial support for SVG 1.1, SVG Animation (SMIL), Fonts, Video and Audio, DOM and style scripting through JavaScript, and more in about a 60K library. Your SVG content can be embedded directly into normal HTML 5 or through the OBJECT tag. If native SVG support is already present in the browser than that is used, though you can override this and have the SVG Web toolkit handle things instead. No downloads or plugins are necessary other than Flash which is used for the actual rendering, so its very easy to use and incorporate into an existing web site.

Raphaël 1.0 RC; Get your graphics on: "

Raphaël uses the SVG W3C Recommendation and VML as a base for creating graphics. This means every graphical object you create is also a DOM object, so you can attach JavaScript event handlers or modify them later. Raphaël’s goal is to provide an adapter that will make drawing vector art compatible cross-browser and easy.
Raphaël currently supports Firefox 3.0+, Safari 3.0+, Opera 9.5+ and Internet Explorer 6.0+.
