It depends what you mean by a graph - a series of vertices (nodes) connected
by edges (e.g. a state diagram) or do you mean the kind of chart you would
produce using a spreadsheet?
For the former, graphviz - a standlone rendering program which uses its own
graph description language (which can easily be generated with PHP). For
the latter, jpgraph - a PHP library.
Try Google for URLs.

In what way better? (SVG is the open standard for scalable vector graphics
and is supported by Graphviz & Mozilla/Firefox - MSIE requires a free
plugin).
