The purpose of dot2tex is to give graphs generated by the graph layout tool
Graphviz_, a more LaTeX friendly look and feel. This is accomplished by:
- Using native PSTricks_ and `PGF/TikZ`_ commands for drawing arrows,
edges and nodes.
- Typesetting labels with LaTeX, allowing mathematical notation.
- Using backend specific styles to customize the output.
Dot2tex can also automatically adjust the size of nodes and edge labels to fit
the output from LaTeX.
