This JavaScript VectorGraphics library provides graphics capabilities for JavaScript: functions to draw circles, ellipses (ovals), oblique lines, polylines and polygons (for instance triangles, rectangles) dynamically into a webpage. Usage of this Vector Graphics library should be easy even if you don’t have JavaScript experience
This is very cool. This javascript graphics libary allows you to draw pretty much any shape, image or text directly into HTML without 3rd party plug-ins like Flash. Speed is amazing and it’s cross-browser compatable too. Get it at  http://www.walterzorn.de
