PHP Chart is an AJAX control for generating dynamic charts and graphics. No PHP GD or any other third party graphic libraries are required on your server. The phpChart has amazing rendering speed because all graphics are completely processed in the Web browser on the client side, thus saving your valuable server resources. It supports all major charting graphs such as pie, bar, scatter, balloon, radar, bubble, zooming, candlestick, block, curve, donuts charts, and much more.
PHPStateMapper is a PHP library for drawing a map with areas shaded by varying degrees of intensity based on data given as a simple list. It exports a PNG image in a configurable size and color. It is appropriate for generating images for use in reporting and analytics. Data can be loaded programmatically or from a comma separated values (CSV) source file.
GLE (Graphics Layout Engine) is a graphics scripting language designed for creating publication quality figures (e.g., a chart, plot, graph, or diagram). GLE supports various chart types (including function plot, histogram, bar chart, scatter plot, contour plot, color map, and surface plot) through a simple but flexible set of graphing commands. More complex output can be created by relying on GLE's scripting language, which is full featured with subroutines, variables, and logic control. GLE relies on LaTeX for text output and supports mathematical formulae in graphs and figures.
