title: How to programatically pan a VisualizationViewer with Jung (the java library)?
body: <p>After a lot a investigations, I don't achieve to find a convenient answer to the following question: how to programatically pan a VisualizationViewer with Jung?</p>
  
  <p>I have a GUI with the list of the vertices of my graph, and I want that a double click on one item of the list (i.e. a node description) perform a "centering action" of my VisualizationViewer for the clicked node.
  How to code such a behavior? it seems simple but I found no convenient answer.</p>
  
  <p>If someone could help, thanks!</p>
