The purpose of dot2tex is to give graphs generated by Graphviz a more LaTeX friendly look and feel. This is accomplished by converting xdot output from Graphviz to a series of PSTricks or PGF/TikZ commands. This approach allows:
- Typesetting labels with LaTeX, allowing mathematical notation.
- Using native PSTricks and PGF/TikZ commands for drawing arrows (optional).
- Using backend specific styles to customize the output
