I'm the author of Grafico, A Raphaël (js based SVG/VML) charting library with a focus on proper charts (per Stephen Few/Tufte) Check it out here: http://grafico.kilianvalkhof.com/ http://grafico.kilianvalkhof.com/ and this page has a lot of examples: http://grafico.kilianvalkhof.com/documentation/index.html http://grafico.kilianvalkhof.com/documentation/index.html It doesn't have pie charts, because pie charts are a tremendously bad way to visualise data. I have barcharts with negatives though :)
