:Title: Snaked edges
:Tags: PGF
This graph uses special `PGF/TikZ`_ styles to create some interesting
visual effects. To get the snaked edges run dot2tex with the ``-s`` option
to force straight edges.
Generated with::
$ dot2tex -s --prog fdp balls.dot > balls.tex
.. _PGF/TikZ: http://www.ctan.org/tex-archive/help/Catalogue/entries/pgf.html
