PHP/SWF Charts is a PHP script and flash file that can build great looking charts. The flash part does all the work. The PHP script just generates the HTML tags to embed the flash file. It can generate a number of different types of charts including line, column, and pie charts.
We're using it at Postica to generate charts for our customers showing statistics on the number of spam and malware blocked, for example.
The state is that great fiction by which everyone tries to live at the expense of everyone else. - Frederic Bastiat
