% Haskell bindings to the Graphviz toolkit % Ivan Lazar Miljenovic
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
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.
