title: Plot edge by size / length in Igraph 0.6 for Python 2.7 (Not for R)
body: <p>It appears that I can't find the solution for the following issue:</p>
  
  <p>I want to plot the edges by size (length, not width).</p>
  
  <p>I mean if the edge between V1 and V2 vertices is a value equal to 20 I would like to plot that edge exactly 20 pixels. </p>
  
  <p>If another edges between V2 and V3 is 60 that edge will be longer in the plot. </p>
  
  <p>I can't find how to specify the edge size or length. Maybe it's not possible with a simple codeline like other attributes for plotting (vertex size, colors, width etc)
  Igraph tutorials didn't give answer to this. Probably it's difficult. </p>
  
  <p>The shape-orientation of graph is not important even if the fixed edges will give a constant shape I guess. </p>
  
  <p>The graph is undirected but has many vertex and edge sequences.  </p>
