title: How to specify the length of an edge in graphviz?
body: <p>In a directed graph, if there is a cycle, the graphviz makes that edge really short.</p>
  
  <p>Is there a parameter that would let me change the length of the cyclic edge, so that 
  the graph looks a bit uniform.</p>
  
  <pre><code>digraph ER {
    rankdir="LR";
    //orientation=landscape;
      node [shape=ellipse, fontsize=30];
    {node [label="Original"] old;}
    {node [label="Final"] new;}
    {node [label="Intermediate"] ir;}
  
  old -&gt; ir [label="suggest", fontsize=30];
  ir -&gt; ir [label="validate", fontsize=30, len=f];
  ir -&gt; new [label = "finalize", fontsize=30];
  }
  </code></pre>
