Description:

Image_Graph provides a set of classes that creates
graphs/plots/charts based on (numerical) data. Many different plot
types are supported: Bar, line, area, step, impulse, scatter,
radar, pie, map, candlestick, band, box & whisker and smoothed
line, area and radar plots. The graph is highly customizable,
making it possible to get the exact look and feel that is
required. The output is controlled by a driver mechanism, which
facilitates easy output to many different output formats, amongst
others, GD (PNG, JPEG, GIF, WBMP), PDF (using PDFLib), ShockWave
Flash (using Ming) and Scalable Vector Graphics (SVG). Image_Graph
is compatible with both PHP4 and PHP5 and can be used with both
GD1 and GD2 (GD2 is recommended)
