Rafaël is a nice SVG libraray as an atelrative for the mode traditionl JavasScript frameworks such as JQuery, Dojo, Mootools and so on. Another alterantive to look at is: svgweb.
Also if you want to work a little with SVG but don't want to do your entire project in it you can look to
Polymap for inspiration of a programmable component to add.
Another really interesting SVG-oriented framework is Paper.js, http://paperjs.org/
ReplyDelete, which is an open source vector graphics scripting framework that runs on top of the HTML5 Canvas. The good thing about this is that you can get vector functionality in browsers that don't support SVG.
