If all you need are time-series graphs, I really like Dygraphs: <a href="http://dygraphs.com/" rel="nofollow">http://dygraphs.com/</a> It doesn't seem to get much love, does anyone know why?
I tried this out once. At the time the CSS wasn't namespaced, and used fairly common class names, so it interfered with other parts of the project. Not sure if it has been fixed since.<p>Eventually went pure D3.
