Module Graphviz

module Graphviz: sig  end

Interface with GraphViz

This module provides a basic interface with dot and neato, two programs of the GraphViz toolbox. These tools are available at the following URLs:

Common stuff

Because the neato and dot engines present a lot of common points - in particular in the graph description language, large parts of the code is shared. The CommonAttributes module defines attributes of graphs, vertices and edges that are understood by the two engines. Then module DotAttributes and NeatoAttributes define attributes specific to dot and neato respectively.

Common attributes

type color = int

type arrow_style = [ `Dot | `Inv | `Invdot | `Invodot | `None | `Normal | `Odot ]

module CommonAttributes: sig  end

The CommonAttributes module defines attributes for graphs, vertices and edges that are available in the two engines, dot and neato.

Interface with the dot engine

module DotAttributes: sig  end

The DotAttributes module defines attributes for graphs, nodes and edges that are available in the dot engine.

module Dot: functor (X : sig  end) -> sig  end

The neato engine

module NeatoAttributes: sig  end

The NeatoAttributes module defines attributes for graphs, nodes and edges that are available in the neato engine.

module Neato: functor (X : sig  end) -> sig  end
