Highcharts is open source, but it has a restrictive license for commercial use. It is free for non-commercial use (personal, non-profit) and it is also free during development, even commercial apps.
I also highly recommend. It's a pleasure to work with. Sites using it include MixPanel if you want to see it in action.
