title: Calculating average shortest path from Graphviz file
body: <p>I am using Graphviz to visualize some relationships as a graph. I also need to calculate the average shortest path and the average clustering coefficient for this graph. I figured there might be some existing tool out there that could do this for me, but I've looked all over and have come up blank. Is there something in Graphviz itself, or another compatible tool, that can do this analysis for me?</p>
  
  <p>Below is an example of the type of file (in their <code>dot</code> language) I have and am looking to analyze.</p>
  
  <pre><code>graph G {
    a -- b;
    b -- d;
    c -- d;
    b -- l;
  }
  </code></pre>
