If you are interested in SVG charting engines, check out Highcharts. Used them on a project recently and really liked how it turned out. It's a shame that VML performance in IE is so terrible when SVG performance in Chrome is so awesome.

Highcharts is definitely one of the most impressive chart solutions I have seen.

I don't remember its VML performance being particularly slow but I do know its' SVG performance screams in IE9.
