[igraph] help with some plots

[simone gabbriellini]

Hello again list,

I was wondering how to do some plots with igraph...

I see Effective diameter - distance at which 90%  of pairs of nodes  
are  reachable - is one of the used plot to display static network  
patterns... is it possible to realize with igraph?

Second question: do you (experts of complex network) use some  
particolar type of plot to display path length patterns in a network  
as node number increase?

thanks,
Simone
