Re: [igraph] igraph visualization

[Ahmed Abdeen Hamed]

Excellent guess and actually that got ride of the error and installed the py2cairo.

However, the plot is still no available:

>>> plot(g, layout = layout)

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "/Library/Python/2.7/site-packages/igraph/drawing/__init__.py", line 427, in plot

    result = Plot(target, bbox, background="">

  File "/Library/Python/2.7/site-packages/igraph/drawing/__init__.py", line 122, in __init__

    self._surface_was_created = not isinstance(target, cairo.Surface)

  File "/Library/Python/2.7/site-packages/igraph/drawing/utils.py", line 396, in __getattr__

    raise TypeError("plotting not available")

TypeError: plotting not available

>>> 

Any more wild guesses? :-)

Maybe you need the python package as well, from brew, but this is just a guess:

brew install python
