Sir, excanvas is as slow as it can get. I am currently working on a web visualization and let me take you to earth, there are two graphic libraries to plot graphs (the ones with nodes and edges, not charts) out there:
1. The distinguished Protovis (http://vis.stanford.edu/protovis/) which doesn't run on some outdated versions of IE8 (and due to company policy I can't run Windows Updates)
2. JIT (http://thejit.org/), which performs poorly (I hardly get more than 2 FPS, whereas in Firefox 3.6 and Chromium Dev it's running well, well over 15 FPS, the target I aim for).
And let me note that making my app work on IE took me two days of work. That is what IE doesn't get and why web developers are mad at IE.
It slows down the pace of amazing UX growth in the web.
