Re: [igraph] bow tie

[Simone Gabbriellini]

Hi,

thanks for your advice.

I think that the important part here is not to plot actual nodes, but
to plot percentage of users in order to check if the in- nodes are
much more than the out- nodes, for instance... the proportions of the
bow tie should be informative in some sense.

Best,
Simone
