Dot documentation
=================

This page documents some tricks I learned when using dot_

.. _dot: http://www.graphviz.org/

Multiple nodes with the same label
----------------------------------

::

    node1 [label = "a"];
    node2 [label = "a"];

    node1 -> node2;

Drawing a tree
--------------

Use dot (standard digraph type). Use the ``orientation`` variable to change the
orientation of the tree

Left to right ordering taken into account
-----------------------------------------

use ``ordering = out;``

Make edges avoid nodes
----------------------

use ``splines = true;``

Avoid overlaping nodes
----------------------

use ``overlap = "scale";``
