Description

This library provides bindings for the Dot language used by the Graphviz (http://graphviz.org/) suite of programs for visualising graphs, as well as functions to call those programs.

Main features of the graphviz library include:

Almost complete coverage of all Graphviz attributes and syntax. Support for specifying clusters. The ability to use a custom node type. Functions for running a Graphviz layout tool with all specified output types. The ability to not only generate but also parse Dot code with two options: strict and liberal (in terms of ordering of statements). Functions to convert FGL graphs and other graph-like data structures to Dot code - including support to group them into clusters - with a high degree of customisation by specifying which attributes to use and limited support for the inverse operation. Round-trip support for passing an FGL graph through Graphviz to augment node and edge labels with positional information, etc.
