title: Displaying 2 graphs using JUNG
body: <p>Using <a href="http://jung.sourceforge.net" rel="nofollow">JUNG</a>, I am able to draw one graph at a time. However, I need to display 2 independent graphs (already populated) by overlapping one over the other (perhaps with different vertex/edge colors). How do I do that? I am not able to see any mechanism to add a new graph to already existing layout.</p>
  
  <p>Does JUNG support this?</p>
  
  <p>Regards,</p>
