PHPGraphLib is a lightweight PHP-based graphing library that creates slick PHP graphs for incorporation into a website or application.
PHPGraphLib is a PHP 4+ friendly object-oriented class that has powerful customization features, allowing you to generate the perfect bar, line, stacked bar, or pie graph for any application. Used with dynamic data, PHPGraphLib allows easy visual interpretation of sophisticated data sets. Simply feed PHPGraphLib an array of data points, and it will generate a .png chart of your data.
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+ compatible. Originally available only for paid commercial use, PHPGraphLib was open-sourced in 2013 under the MIT License. Please visit http://www.ebrueggeman.com/phpgraphlib for more information.
