[igraph] using the Graph.layout_drl function

[Kurt J]

Hello,

I've just recently been playing with the python igraph interface.  I
want to do a graph layout on a network w/ about 70k nodes.  The layout
algorithm seems to complete.  But the layout has a massive vertical
line of nodes in the middle.  That is, many nodes seems to retain an
"x" value of near zero in the layout.

Is this normal?  Is there an easy fix?  Is there more info on the DrL algorithm?

Thanks!
