Hi, Guido

I don't know other packages, but igraph (R package) can do similar stuff. It
has tcl/tk interactive mode, but you can move the nodes to generate a
goodlook netowrk. In other words, length of edge can be manually adjusted,
however, you can use the width of edge for your index scores. The details
can be found in the manual.

Best

Gilbert
