Seems like http://dev.markitondemand.com/, Highcharts JS, (although it is quite large and they do charge a fee), AMcharts, Kraken, and Fusioncharts are the frontrunners on DuckDuckHack. We'll update this thread when they are more suggestions, though this should be enough to set the project in motion.
