how to draw a graph (nodes and arcs)?

[_andrea.l]

I'd like to draw a graph using a different pictures for each node.
How can I do?
I'd like to link the nodes and the arcs.
There is a library for doing that?
if it not exists what is the best algorithms for doing that?
Thank you in advance,
Andra.

Either use GD for painting the nodes and lines over a image canvas (see the
PHP's image functions) or use the <canvas> element (firefox- and
safari-compliant).
