Raphaël is a small library (20 kilobytes) for building vector graphics on websites.
It uses SVG and VML as a base for creating graphics. Given that each created object is a DOM object, using JavaScript handlers, you can easily change their properties and actions. So a bunch of Raphaël + jQuery will provide great opportunities for development.
According to the author, the library works in all major browsers: Firefox 3.0+, Safari 3.0+, Opera 9.5+ and Internet Explorer 6.0+, and also add Chrome myself. ')
With the help of this library you can create truly amazing things, such as: text unfolding, dynamic images, interactive graphics, etc.
I strongly advise you to look at examples of things that can be done, the links to which are listed below - this will not leave you indifferent ;-)
