Tibco Spotfire's professional client and web player are great tools, but very expensive. I'd like to find an open-source, browser-based (ideally JavaScript) alternative for creating feature rich charts with minimal configuration. The ideal solution would have the following characteristics:

  • Support for bar charts, scatter plots, box plots, and heat maps.
  • Custom tooltips.
  • Zooming/panning.
  • Brush selection.
  • Ability to pass data from chart to other JavaScript functions.

I cannot count the number D3-based libraries I have looked at, none of which seem to support all of the above features. Do any open source alternatives to Spotfire exist?

  • Here is a comparison of JS charting frameworks - it is somewhat limited in feature comparisons, but you may find helpful. en.wikipedia.org/wiki/… – Merrily Sep 9 '14 at 0:00
