Print graph in NetworkX

Question

Is there a way to pretty print a graph in NetworkX? For example:

>>> import networkx as nx >>> G = nx.Graph() >>> G.add_edge('Alan', 'Bob') >>> G.add_edge('Alan', 'Charles') >>> G.add_edge('Alan', 'Xavier') >>> G.add_edge('Charles', 'Xavier') >>> G.add_edge('Joan', 'Xavier')

I would then like to see this graph as a json-like object, for example:

{ 'Alan': { 'Bob': {}, 'Charles': { 'Xavier': {} }, 'Xavier': {}, }, 'Joan': { 'Xavier': {} } }

It doesn't have to be exactly like the above, but should give a good high-level data view of the graph (provided it's relatively small).

Can you provide and example of the printing you'd like to see? — Scott Boston

@ScottBoston -- sure, I've updated the question with a better example. — samuelbrody1249

In newtorkx version 2.3, there is a method nx.to_dict_of_dicts:

nx.to_dict_of_dicts(G)

Output:

{'Alan': {'Bob': {}, 'Charles': {}, 'Xavier': {}}, 'Bob': {'Alan': {}}, 'Charles': {'Alan': {}, 'Xavier': {}}, 'Xavier': {'Alan': {}, 'Charles': {}, 'Joan': {}}, 'Joan': {'Xavier': {}}}
