NLP.GenI.Graphviz

Graphviz is an open source tool which converts an abstract representation of a graph (node foo is connected to node bar, etc.) into a nicely laid out graphic. This module contains methods to invoke graphviz and to convert graphs and trees to its input format.

You can download this (open source) tool at http://www.research.att.com/sw/tools/graphviz

Documentation

class GraphvizShow b where

Data structures which can be visualised with GraphViz should implement this class. Note the first argument to graphvizShowGraph is so that you can parameterise your show function (i.e. pass in flags to change the way you show particular object). Note that by default, all graphs are treated as directed graphs. You can hide this by turning off edge arrows.

Methods

graphvizShow :: b -> Text

toGraphviz

Arguments

:: GraphvizShow a

=> a

-> String

the dotFile

-> String

-> IO FilePath

Note: the dotFile argument allows you to save the intermediary dot output to a file. You can pass in the empty string if you don't

gvShowTree

Arguments

:: GraphvizShowNode n

=> Text

node prefix

-> Tree n

the tree

-> DotSubGraph Text

Displays a tree in graphviz format.
