pChart

Chart is a PHP class that uses the Open Flash Chart, these graphs are static, and therefore not interactive, since they are generated as PNG-formatted image files. pChart retrieves data to generate the graph through SQL, CSV files, or by manually entering source code. Line graphs, bar graphs, and pie charts are some of the styles that pChart can generate for you. Around twenty examples are included inside the compressed file that comes with pChart. Another class similar to the two previous ones is Ajax MGraph, which combines CSS and AJAX to produce dynamic graphs.
