Drawing on screen

As I understood I can simply call graph_tools.draw.graph_draw(g) and it
should get drawn on a screen. But I get this error when I don't specify the
'output' parameter (i.e just call the function with the graph object).

Error:

Couldn't recognize the image file format for file
'/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/graph_tool/draw/graph-tool-logo.svg

I believe the librsvg library is missing in your system...
