title: graphviz embed svg images
body: <p>I am trying to generate a diagram with embeded svg images.
  If I run graphviz with the regular svg command, the images are only referenced. </p>
  
  <p><code>dot -Tsvg diagram.dot -O</code></p>
  
  <p><a href="http://www.graphviz.org/content/help-embedding-svg-files" rel="noreferrer">Here</a> it says to build with <code>-Tsvg:cairo</code> but I get the following:</p>
  
  <p><code>dot -Tsvg:cairo diagram.dot -O</code></p>
  
  <pre><code>Warning: No loadimage plugin for "svg:cairo"
  </code></pre>
  
  <p>I have lib cairo installed, so I don't know what I am missing.</p>
  
  <p>I am using ubuntu 12.04 LTS, I asked the same question in the askubuntu but there aren't any graphviz tags there.</p>
