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
type t 
module V: sig .. end
module E: sig .. end
val iter_vertex : (V.t -> unit) -> t -> unit
val iter_edges_e : (E.t -> unit) -> t -> unit
val graph_attributes : t -> Graphviz.DotAttributes.graph list
val default_vertex_attributes : t -> Graphviz.DotAttributes.vertex list
val vertex_name : V.t -> string
val vertex_attributes : V.t -> Graphviz.DotAttributes.vertex list
val default_edge_attributes : t -> Graphviz.DotAttributes.edge list
val edge_attributes : E.t -> Graphviz.DotAttributes.edge list
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
type t 
module V: sig .. end
module E: sig .. end
val iter_vertex : (V.t -> unit) -> t -> unit
val iter_edges_e : (E.t -> unit) -> t -> unit
val graph_attributes : t -> Graphviz.NeatoAttributes.graph list
val default_vertex_attributes : t -> Graphviz.NeatoAttributes.vertex list
val vertex_name : V.t -> string
val vertex_attributes : V.t -> Graphviz.NeatoAttributes.vertex list
val default_edge_attributes : t -> Graphviz.NeatoAttributes.edge list
val edge_attributes : E.t -> Graphviz.NeatoAttributes.edge list
end) -> sig .. end
