title: Java Library for conversion from dot to xdot
body: <p>I am currently developing a webapp in Java for which the main output is a graph in the dot-format. For the visualization part I want to use CanViz which needs xdot as input. So far I couldn't find any Java-Library which converts dot to xdot.
  Does anyone know such a Library?</p>
  
  <p>I already tried running "dot graph.cv -Txdot -ograph-xdot.gv" via exec, unfortunately that did not work. (Cannot run program "dot": error=2, No such file or directory)</p>
  
  <p>Thanks in advance,
  Moritz</p>
