Out of curiosity, has anyone looked at re-doing the rendering engine of this in SVG? Now that SVG will be officially supported in IE9, its practicality for web apps is much more substantial. Issues like hit testing/item addressability/animation, conditional display based on zoom level, and other characteristics of smart graphs such as these are generally MUCH easier to do in SVG than by trying to write a ton of JavaScript code to render onto a canvas.
