title: Doctrine: Visual Entity Map
body: <p>"Out of the box", does Doctrine have any support for creating a <a href="http://en.wikipedia.org/wiki/Directed_graph" rel="nofollow">directed graph</a>, <a href="http://en.wikipedia.org/wiki/Unified_Modeling_Language" rel="nofollow">UML</a> or other visual representation of the entity relationships defined in the Doctrine configuration files?  That is, if I'm working with an existing Symfony (or other MVC framework using doctrine) project, is there anything like</p>
  
  <pre><code>//pseudo code
  $graph = $entityManager-&gt;generatedEntityDiagram();
  file_put_contents('graph.dot', $graph);
  </code></pre>
  
  <p>If not, is there known science for doing something like this?</p>
  
  <p>The specific problem I'm trying to solve is taking on an unfamiliar Symfony2 project, with many bundles, and getting a high level overview of the Doctrine object relationships so I can better understand the domain model of a project. </p>
