PHP Social Network Visualizer in Graphviz

I need a PHP class that can examine the social network structure in the PHP5 open source software package AroundMe version 6.9, and, using the graphviz package, generate a few graph visualizations of the resulting social network, in PNG format output.? ? ? These graphs would show the direct social network,? i.e. me, friends, friends of friends, etc, and relationships with groups. A fun project for an experienced PHP programmer.? ? ? ? ## Deliverables This is a programmer to programmer project...No hand holding needed...just a solid deliverable..Any questions or issues can be resolved quickly.? I am easy.? This is an intellectually challenging project.? ? The programmer should be willing to do a little research on visualization of? social networks...There may already be some code out there. I'm not 100% of how the graphs should best look - programmer creativity and feedback welcomed.? ? ? This can be negotiated before closing.
