PHPGraphLib Graphing Library
The first version PHPGraphLib was written in 2007 by Elliott Brueggeman to
deliver PHP generated graphs quickly and easily. It has grown in both features
and maturity since its inception, but remains PHP 4.04+ compatible. Originally
available only for paid commerial use, PHPGraphLib was open-sourced in 2013
under the MIT License. Please visit http://www.ebrueggeman.com/phpgraphlib
