PHP Graphs With GD Library

PHP, with the help of the GD Graphics Library, can dynamically generate graphs and charts from data sets and databases. A relatively simple PHP script can be written to gather data statistics from the database, define the graph size and intervals, and plot line or bar graphs onto a PNG image. The image is created dynamically server-side and then displayed to the end user on page load. This tutorial http://www.techrepublic.com/article/create-graphics-on-the-fly-using-php/5092227 on making graphs with the GD Library from Tech Republic was extremely informative, well written, and easy to follow.
