Dear all,
I'm doing some experiments with igraph and in particular with graph layouts.
I can't figure out how to apply a layout to a given (real) graph avoiding
node overlaps.
In the following example if the variable NumOfNodes is setted to a small
value (10) the
layout function generates a plot without node overlaps. But even with a
not-so-big number
of nodes (50) plotted graph has almost all nodes overlapped by neighbors
vertices.
The problem gets even worst if I increase vertex size.
# R code
require(igraph)
NumOfNodes <- 10
g <- barabasi.game(NumOfNodes)
g$layout <- layout.reingold.tilford(g)
plot(g)
NumOfNodes <- 50
g <- barabasi.game(NumOfNodes)
g$layout <- layout.reingold.tilford(g)
plot(g)
Actually I'm using GraphViz which has an option to avoid overlaps but I
can't find
something similar in igraph documentation.
Can someone point me to the rigth direction ?
Thank you in advance.
