canto.js: An Improved HTML5 Canvas API (via) Improved is an understatement: canto adds jQuery-style method chaining, the ability to multiple coordinates to e.g. lineTo at once, relative coordinate methods (regular Canvas does everything in terms of absolute coordinates), the ability to use degrees instead of radians, a rounded corner shortcut, a more convenient .revert() method and a simple parser that can understand SVG path expressions! The only catch: it uses getters and setters so won’t work in IE.
