I've been interested in Canvas for a while, but I held off on using it because a lot of F.U.D.'ed support for canvas in IE. Well, it turns out that Microsoft Has had support for
Vector Graphics for quite a while. After firefox et al. started using canvas, people at google became interested in it, and wrote a
wrapper for IE. It turns out that through VML, a majority of the canvas functionality was already available in IE. I'm playing around with visualization, and as soon as I have a sample project set up, I'll post more on this topic.
