Re: [igraph] vertex overlap layout

[Bruno Contreras Moreira]

OK,
I have finally managed to plot a graph with a predefined layout, without 
vertex overlap. Thanks for your help.
However, there is one more problem.
If the plot is generated with RESCALE=TRUE, I get a scaled layout with 
visible vertex frames,
but it is not possible to see edges among neighboring vertices, as they 
get hidden I guess.
On the other hand, if I apply RESCALE=FALSE vertices actually loose 
their frames, regardless of their shape, but I can see all edges.
I will like to have both things (all edges and vertex frames), can you 
suggest a solution for this?
