Visual representation of nodes in Python
<p>I have data that I want to represent visually. The actual data is a tree made up of nodes. Each node has a bunch of data associated with it, but as far as this question goes, I just want a way to represent a tree visually using Python. Any ideas?</p>

<p>The different solutions that popped in my head were to use a GUI library like WxPython or PyQT, or maybe even a PDF generator like ReportLab. I'm hoping there's a library out there that deals closer with data so that I don't have to think out the plotting locations of all the nodes.</p>
