Raphaël is a small JavaScript library that should simplify your work with vector graphics on the web. If you want to create your own specific chart or image crop and rotate widget, for example, you can achieve it simply and easily with this library.

You will need to created a canvas object on which to draw then all future calls to drawing methods will be bound to this canvas. Objects created with Raphaël are DOM objects and you can use JavaScript to modify them later.
