[igraph] Ego-centric graphing using weighted edges

[Rick Welykochy]

Hi all,

I've been playing with the F-R algorithm with weighted edges
to layout time series data.

The graph nodes are individual time series and the weighted
edges are the cross correlations between two time series.

F-R does lay the graph out in a pleasing format, but I'm after
more.

I would like to nominate a node to be the centre of the graph
and have the layout chose the distance of neighbouring nodes
to be directly proportional to the strength of the edge
weight. The more two nodes correlate, the closer together
they are.

Perhaps F-R is not suited for this task. Any recommendations
on a layout algorithm (and graph package if not igraph) to
accomplish this?

tia,
rick w
