title: Are there any PHP code visualization tools?
body: <p>Looking for software that will analyze php code (i.e. all of wordpress or the thematic theme) and show me pretty pictures (perhaps a <a href="http://commons.wikimedia.org/wiki/Block_diagram" rel="noreferrer">block diagram</a>) of all the connections to help me more quickly get an understanding of where things are and what's connected to what.</p>
  
  <p>Ideally, this software would run on a Mac, but I'll take anything: Windows, Linux, web-based, etc.</p>
