I think graphviz does something similar, just by the look of it, so
you might want to try it. It has bindings from R, and I am sure that
there are Python bindings for it, too.

More seriously, visualization has not been the main focus of igraph so
far, other packages like graphviz or gephi are better suited for
drawing graphs in sophisticated ways.
