% Haskell bindings to the Graphviz toolkit % Ivan Lazar Miljenovic

The graphviz Library

The graphviz library provides bindings to the Graphviz graph visualisation suite of tools for the purely functional programming language Haskell. It can be downloaded from HackageDB or - if you have cabal-install - installing it is as simple as:

cabal update
cabal install graphviz

Library features

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.
