what exactly do you mean by this? You need a way to smartly place the
nodes for drawing the graph? You did not tell us whether you want to
use R or Python. In R this would be something like:

pos <- layout.fruchterman.reingold(mygraph)
plot(mygraph, layout=pos)

Check the documentation for the various plot options at
http://igraph.sourceforge.net/doc/R/layout.html or type

help("layout.kamada.kawai")

in your R session. See also the plotting parameters at
http://igraph.sourceforge.net/doc/R/plot.common.html or type

help("igraph.plotting")
