Generic Function Graph->Dot (5 methods)
(
graph->dot < graph > < output > &key < graph-formatter > < vertex-key > < vertex-labeler > < vertex-formatter > < edge-key > < edge-labeler > < edge-formatter > )
Generates a description of `graph` in DOT file format. The formatting can be altered using `graph->dot-properties,` `vertex->dot,` and `edge->dot` as well as `edge-formatter,` `vertex-formatter,` `vertex-labeler,` and `edge-labeler`. These can be specified directly in the call to `graph->dot` or by creating subclasses of basic-graph, basic-vertex and basic-edge.
The output can be a stream or pathname or one of the values `nil` or `t`. If output is `nil`, then graph->dot returns a string containing the DOT description. If it is `t`, then the DOT description is written to *standard-output*.
Here is an example;
(let ((g (make-container 'graph-container :default-edge-type :directed)))
(loop for (a b) in '((a b) (b c) (b d) (d e) (e f) (d f)) do
(add-edge-between-vertexes g a b))
(graph->dot g nil))
“digraph G {
E []
C []
B []
A []
D []
F []
E->F []
B->C []
B->D []
A->B []
D->E []
D->F []
}”
