Re: [igraph] Tethered network graphs

Hi Chris,

the Fruchterman-Reingold layout generator can take edge weights, and
the "forces" used to generate the layout are proportional to these
weights. There is no guarantee that your central node will be in the
middle, but I guess there is a good chance for it.

Best,
Gabor
