Hello,
I'm using graph_tool in a scenario, in which the meaning of a vertex cannot be easily be explained by a label or a text. To get a meaningful graph I would need to display a image inside the vertices. Has anyone an idea, how could this be achieved?
Thanks

Just use the "vertex_surface" option in graph_draw(). It should be either a cairo surface, or the file name of an image.
See here for a concrete example:

Cool, that solved it! Thanks!

Hi Tiago,
I set "vertex_surface" propertymap when visualizing the graph, but in addition to the Image I load, the circle shape is also shown as the background of a vertex. What was I wrong? Thanks.
