title: Graphviz - how to display the edge count for concentrated edges?
body: <p>I have a directed graph that concentrates overlapping edges on to one edge. A sample .dot file is given below:</p>
  
  <pre><code>strict digraph Test {
  concentrate=true
  A -&gt; B;
  A -&gt; B;
  A -&gt; B;
  }
  </code></pre>
  
  <p>I would like to display the number of overlapping edges as the edge label. This sounds pretty trivial, but I haven't been able to figure out how to do this. Is this possible? If possible how do I do it? </p>
  
  <p>Thank you.</p>
