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.

Well, go for it, then, patches are welcome. :)
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.
