Flotr is a library for Prototype and Mootools which has interesting features :

• The text can be drawn on the graph (not as DOM text, so that the user can save the image)
• A very helpful and interactive configurator
• Time series
• Zoom, mouse drag, etc : http://phenxdesign.net/projects/flotr/examples/prototype/
• An integrated spreadsheet
• Cross browser, free and open source

Answer 10

Nobody (yet) mentioned Protovis, checkout the Examples, graphs similar to Google Finance can be created by combing Focus+Context and Playfair's Wheat.
