:Title: Node drop shadows
:Tags: TikZ


The ``tikz`` output format is highly customizable thanks to TikZ' powerful
style options. In this example drop shadows have been added to all the nodes.

**Note**: This example requires PGF 2.00 or later. Download the PDF to fully see
the drop shadow effect. The bitmap rendering does not render transparency well. 


Generated with::

 $ dot2tex -ftikz --prog neato -s --crop dropshadows.dot > dropshadows.tex
