pChart is a PHP class oriented framework designed to create aliased charts.

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.
