Graidle

Graidle (Graph aid) is a Web application for creating charts. It can be used to generate several types of graphical diagrams. It has classes specialized in generating histograms (also horizontal), spider graphs, pie charts, and line (also filled) charts. Several visual aspects may be customized, such as colors, font dimensions, labels, and axes. The diagrams are generated as true color images using PHP and GD library functions, and can be displayed as the current script output or saved to a file in the PNG format.
