I did the same as this guy. My conclusions Flot (mentioned in his previous article) still kicks ass but needs a bit more work. Emprise is really nice if you are happy to pay. Personally I think Flot does an equivelent job for free. Although, Emprise also includes some stuff to compute trends which flot doesn't. Raphaël is totally bad ass, but it's for hand rendering specific data more than just charting since there are little in the way of helper functions for that. That said check this out, it's awesome http://raphaeljs.com/github/impact.html http://raphaeljs.com/github/impact.html
