title: Average path length of a network graph?
body: <p>I have this network graph:</p>

  <p>I created a distance matrix based on each vertex:</p>

  <p>What i want to do now is to find the <strong>"average path length"</strong> of the network graph above, but the definition says <strong>"the average length of shortest path between any two vertices"</strong>. I couldn't work my head around that definition and was wondering if anyone could help me out on this.</p>
