That's horrible. Instead of drawing graphs on the client side, you're pushing insanely large number of images to the browser. It makes sense for google maps, not for graphs.<p>Plus you can't do any animation, changes to the graphs on the fly.
The idea that Seadragon is a platform that can be compared with Flash and Canvas is such crap. Its just a library for zoomable maps (which you've been able to create for years with the google maps API since 2005 or something).
