Two.js[1] has a WebGL renderer and abstractions for basic vector graphics and polygons. I haven't had the chance to use it in a project yet but it seems promising. Two.js could even be used as a basis for a WebGL charting library (thus providing another layer of abstraction).

Thanks, that sounds really promising, will give it a try!
