title: Plotting graph from adjacency matrix
body: <p>I have a graph in an adjacency matrix format: </p>
  
  <p><code>https://dl.dropboxusercontent.com/u/22681355/network.csv</code></p>
  
  <p>The nodes in the first column are connected to the corresponding nodes in the second column.</p>
  
  <p>Is it possible to convert this graph to a format that makes it possible to visualize?</p>
