Seems like there should be a method in networkx to export the json graph format, but I don't see it. I imagine this should be easy to do with nx.to_dict_of_dicts(), but would require a bit of manipulation. Anyone know of a simple and elegant solution?

This documentation contains a full description

A simple example is this:

import networkx as nx
from networkx.readwrite import json_graph

DG = nx.DiGraph()
DG.add_edge('a', 'b')
print json_graph.dumps(DG)

You can also take a look at the Javascript/SVG/D3 nice example on adding physics to the graph visualization.
