title: Plotting network / relationship / connection type graphs in Python
body: <p>Does anyone know a library to plot relationships between various items to show visualize their interconnectedness in Python? </p>
  
  <p>I don't even now what these graphs are called. The best example is something like <a href="http://www.visualthesaurus.com/" rel="nofollow">Visual Thesaurus</a>. </p>
  
  <p>I'm somewhat familiar with Matplotlib but haven't seen this type of plot. </p>
