A js graphical library for drawing charts. It stands on top of jQuery, MooTools or Prototyp, depending on the host project fundations, and provides a large serie of nice colored animated charts.
Another js charting library. But this one doesn't use canvas nor SVG, it creates png as dataurls, and seems rather fast. The main forepoint is that it works out of the box in most of the browsers of the market.

about:
The sfStatsPlugin provides an easy way to display charts based on data you already own. Whether you want to follow the global progress of your application usage, or to analyze precisely how many specific actions were done by users under particular conditions, this plugin is for you.
Server-based solutions, implemented with Flash, JavaScript or pure CSS, offer a more flexible alternative. In fact, since Flash offers significant advantages over static data presentation with CSS and JavaScript, most solutions use it for dynamic data visualization. The data itself is often stored in XML-files which are loaded and updated via PHP or ASP. The price range varies enormously — depending on the flexibility and level of customization you’d like to have. However, if you don’t want to pay, you don’t have to — there are powerful free solutions as well.
