“PHP/SWF Charts brings interactive eye candy to your charts and
graphs. This PHP tool generates 20 types of charts, including line,
column, 3-D column, pie, 3-D pie, bar, scatter, and polar
charts.“Rather than creating simple images, PHP/SWF Charts outputs
Flash movies, which you can view in a browser that’s running at
least version 6 of Adobe Flash Player. You can click and drill down
on the charts, which feature animated transitions and present
values on mouse hover. You can update the charts with live data
without reloading the page…”
