@hackage graphviz2999.7.0.0

This library provides bindings for the Dot language used by the Graphviz (http://graphviz.org/) suite of programs. Also provided are convenience functions to convert FGL graphs into Dot code with a large degree of customisation for layout, etc. Also allows a limited amount of parsing of Dot, and round-trip usage of Graphviz to attach positional data to each node and edge in the graph.
