Mathematica SpringEmbedding Parameters

I'm trying to construct a 3D graph in Mathematica, where the actual lengths of the edges are important. Taking a look at their documentation for graph drawing (http://www.wolfram.com/learningcenter/tutorialcollection/GraphDrawing/GraphDrawing.pdf) I found that the Spring Embedding Algorithm might best suit my needs. The algorithm they mention specify a parameter R and a set of natural lengths for each edge. However, I do not know how to actually use these in Mathematica. The code I use is

GraphPlot[adj_mat, Method->"SpringEmbedding"]

and cannot find any way to alter the natural lengths or the parameter R. Does anyone know how to set these values?

Thank you!

Look up the documentation under GraphLayout and you will find many examples. Here is a brief code on how to use the layout specifiers with GraphPlot:

edge = RandomInteger[#] \[UndirectedEdge] # + 1 & /@ Range[0, 15];
weight = RandomInteger[{1, 5}, 16];
gr = Graph[edge, EdgeWeight -> weight];
GraphPlot[gr, 
   Method -> {"SpringEmbedding", "EdgeWeighted" -> #}] & /@ {True, 
  False}
