Creating a flowchart from a Polyrex document

Given the [flowchart](http://jamesrobertson.eu/svg/2012/jun/07/local_file_flowchart.svg) I created yesterday I've had an idea about how I could create a flowchart from a Polyrex document.

Here's how the flowchart would appear as a decision tree:

Here's how it would look as a raw Polyrex document in plain text.

    <?polyrex schema="tree/entry[item]"?>
    known route
      run job
      plink address?
        run job
        local file?
          return contents
          return 404
    
Given the above Polyrex document a flowchart could be generated automatically.
