Ask HN: What open source packages are available to display chart and graphs?

Google provides an API to create charts. But it's hosted by Google. What alternative options are available to display charts on a web based application?

Highcharts is my fav and default charting library.

http://www.highcharts.com

Highcharts is not open source but is free to use for non-commercial use. I have paid the $80 to use it on commercial websites and client/managers are always very impressed with its capabilities. I think its well-worth the $$

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.

For time-series, I like dygraphs: http://dygraphs.com/

For server-side chart generation, I tend to use matplotlib (semi-recently changed from gnuplot).

One option, depending on the type of chart your looking for, might be the Javascript InfoVis Toolkit: http://thejit.org/
