Thanks for the feedback. Please check out another project of mine, Envision.js: http://humblesoftware.com/envision/

Envision is a visualization toolkit for fast composite, interactive and animated visualizations. It's adapted to work with Flotr2.

Flotr2 & envision support Android, iOS and new Blackberries, any modern browser with Canvas, and IE7+ with FlashCanvas / excanvas. I've seen it in IE6 too, but I do not test that browser.
