What could cause NetworkX & PyGraphViz to work fine alone but not together?

Question

I\'m working to learning some Python graph visualization. I found a few blog posts doing some things I wanted to try. Unfortunately I didn\'t get too far, encountering this

Answer 1

nx.nx_pydot.graphviz_layout() seems to be the way to use graphviz_layout in Networkx release 1.11.

You may need to install Graphviz via

sudo apt-get install graphviz

Some example code from the documentation:

import networkx as nx
G = nx.complete_graph(4)
pos = nx.nx_pydot.graphviz_layout(G)

I suggest this as the Graphviz_layout documentation for 1.11
