You can try experimenting with redrawing the graph after every 10  
Fruchterman-Reingold iterations or so (and of course passing the  
_previously shown_ layout as seed to the calculation). igraph performs  
500 iterations per default, but you can control that by the maxiter  
keyword argument passed to Graph.layout.
