Re: drawing of network: in search of a tool

For visualization purposes, I want to draw a power system with the power flows on the figure.

* nodes on specific coordinates
* make connections between them according to the connections in my network
* put a number and arrow next to the connections indicating the power flow
* put a number next to every node (for voltages)
* preferably a vector format output for

All the input data is available in matlab, csv or txt format.

The visualisation should be possible for large networks, without cluttering of information, and it should be ideal as this could be done using some script in post-processing. It would be nice if it was very straightforward :-). If the result is a figure, that is ok (no need for interactivity with the outcome).

We've done things like this on numerous occasions with the Carter Butts 'sna' package for R. Fixed nodes, network node/edge lists, numbers and arrows, directed graphs, edge weights, etc.

Output as whatever you like that R supports - postscript, pdf, bitmap, jpeg, blah blah blah. :-)

See page 8 of this PDF for some things generated by R and r/sna:
