PHPGraphLib - Lightweight PHP Graphing Library

PHPGraphLib is a PHP 4.3+ friendly object-oriented script that has powerful customization features, allowing you to generate the perfect graph for any web site or application. Best used with dynamically data, PHPGraphLib allows easy visual interpretation of sophisticated data sets. Simply feed PHPGraphLib an array of data points, and it will generate a .png image of your data. At less than 25kb in size, it will not slow down your scripts. If no customizations are made, PHPGraphLib adjusts the scale and axis of the graph to fit any data, including large numbers, decimal numbers, and negative numbers. PHPGraphLib supports multiple data sets, line graphs, point graphs, bar graphs, and pie charts.
