Display graph without saving using pydot

Here’s a simple solution using IPython:

from IPython.display import Image, display

def view_pydot(pdot):
    plt = Image(pdot.create_png())
    display(plt)

Example usage:

import networkx as nx
to_pdot = nx.drawing.nx_pydot.to_pydot
pdot = to_pdot(nx.complete_graph(5))
view_pydot(pdot)
