Web Applications Stack Exchange is a question and answer site for power users of web applications. It's 100% free, no registration required.

Good online visualization\charting API is a great time saver when building a site. It spares the need to install libraries, handle with image files, and write lots of boilerplate code.

Criteria for good answers:

  • Good looking
  • Free
  • Stable API and Site (unlikely to disappear anytime soon, leaving my site without charts)
  • Good SLA
  • Easy to learn
  • Variety

One tool per answer please, and images are really welcome!


PS Admins, please retag my question with "chart" and "visualization"
