Images in vertices

graph-tool

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:

Best,

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.
