Parses the Graphviz DOT language and creates an interface, in golang, with which to easily create new and manipulate existing graphs which can be written back to the DOT format.

This parser has been created using gocc.

Example (Parse and Edit)

graphAst, _ := gographviz.ParseString(`digraph G {}`)
graph := gographviz.NewGraph()
if err := gographviz.Analyse(graphAst, graph); err != nil {
graph.AddNode("G", "a", nil)
graph.AddNode("G", "b", nil)
graph.AddEdge("a", "b", true, nil)
output := graph.String()



go get
