title: draw binary tree with php
body: <p>I'm looking for a good library / API to draw a binary tree using PHP.
  I've tried using Image_GraphViz, but it doesn't seem to work. I've also looked at phpsyntaxtree, but its not documented.</p>
  
  <p>Alternatively, I'm also looking for a jQuery plugin that does this. (just not <a href="http://frank-mich.com/jQuery/" rel="nofollow noreferrer">this one</a> because it has <strong>no</strong> documentation).</p>
  
  <p>Thanks</p>
