Module Document.Graph

Graph Builder

A convenient module for building simple graphs and turning them into Graphviz code.

• Use Graph.e ?lbl source_name destination_name to describe an edge of the graph (with an optional label).
• Use Graph.n ?lbl node_name to describe a node of the graph (with an optional label). Note that nodes that appear in at least one edge are not required to be specified with n.
• Use Graph.set_graph_name s (at most once) to give a name to the graph.

Example:

type g = { edges: (int * int) list; }

#program;;
let g_to_doc g =
  let module D = Document in
  D.Graph.(to_doc @@ List.map (fun (a,b) -> e (Int.to_string a) (Int.to_string b)) g.edges)
;;

#install_doc g_to_doc;;

{edges=[1,2; 3,4; 1,4; 2,10; 10,1; 3,2; 4,10] };;
