A Really Powerful Vector Javascript Library

Raphaël is a small JavaScript library that should simplify your work with vector graphics on the web. In case you want to create your own specific chart or image crop-n-rotate widget, you can simply achieve it with this library. Raphaël uses SVG and VML as a base for graphics creation. Because of which every created object is a DOM object so you can attach JavaScript event handlers or modify objects later. Raphaël’s goal is to provide an adapter that will make drawing cross-browser and easy. Currently library supports Firefox 3.0+, Safari 3.0+, Opera 9.5+ and Internet Explorer 6.0+.
