But note, that if you set too small bounaries, e.g. you set constant edge length L, many graphs can not be drawn this way. Hi,

You can also check the <a href="http://blog.ivank.net/force-based-graph-drawing-in-javascript.html" rel="nofollow">JavaScript version</a>. I have implemented this algorithm in 6 or 7 languages including C#. I am sure you just have some minor mistake - plus instead of minus or something. Look at it again, carefully! :) Hello,

I didn't try it yet, but my novice approach would be just using the number of edges between two vertices as a factor to multiply with. Would that work ? any better ideas ?

You can do it simply by incidence matrix made of integers, which mean number of edges between two vertices. Then draw several different arcs between two vertices, instead of one line. I was drawing oriented graphs with arcs in my <a href="http://sm.ivank.net/" rel="nofollow">SM Tool</a> (you need Silverlight plugin to see it). hi Michel, I have never heard about multigraphs and I am reading about it on wikipedia right now.
