I've installed python iGraph and its dependencies to try it out. I have been going through the tutorial and I get an error message when I try to plot the graph.

Here is the simple code I used from the tutorial:

>>> from igraph import *

>>> g = Graph([(0,1),(0,2),(2,3),(3,4),(4,2),(2,5),(5,0),(6,3),(5,6)])

>>> g.vs["name"] = ["Alice", "Bob", "Claire", "Dennis", "Esther", "Frank", "George"]

>>> g.vs["age"] = [25, 31, 18, 47, 22, 23, 50]

>>> g.vs["gender"] = ["f", "m", "f", "m", "f", "m", "m"]

>>> g.es["is_formal"] = [False, False, True, True, True, False, True, False, False]

>>> layout = g.layout("kk")

When I do the next command:

>>> plot(g, layout = layout)

I get this error message:

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "build/bdist.macosx-10.5-x86_64/egg/igraph/drawing/__init__.py", line 446, in plot

  File "build/bdist.macosx-10.5-x86_64/egg/igraph/drawing/__init__.py", line 117, in __init__

  File "build/bdist.macosx-10.5-x86_64/egg/igraph/drawing/utils.py", line 396, in __getattr__

TypeError: plotting not available

I am not sure why I am getting this? I would appreciate any advise.
