Charting /Data Visualization Libraries.

Hello,

I like to display interactive graphs on a web page using Rails framework. Can you please suggest javascript library which is well integrated with Rails? I found cool widgets from YUI or Google Visualization. Anybody has experience using google visualization through Rails?

Thanks, -Meera

Open Flash Chart is well integrated with Rails thanks to the plugin made by PullMonkey ( http://www.pullmonkey.com ) but as the name indicates it, it is a flash library not a javascript one even if you can use js to dynamically update the json data used by OFC.
