Greetings,
I have been unable to see any effect on the layout when using the 'groups' argument.
For example, I have tried setting groups equal to a VertexPropertyMap as follows:
vprop_layout_groups = self.new_vertex_property("int") # Vertex groups.
With layout_groups = [0 0 0 0 0 0 1 1 1] I can see no grouping effect on the positions of the vertices as returned by sfdp_layout(). The three vertices without edges are in the '1' group. The connected vertices are in the '0' group. https://nabble.skewed.de/file/t496263/sfdp-groups.png I have been unable to find any example showing a call to sfdp_layout() where 'groups' is used. Is there a working example available?
Thank you.
p.s. Is there a way to donate money to the graph-tool project?

You should experiment with the `gamma` parameter which controls the strength of the attractive force between nodes of the same group.
