go-dot

Simple dot file writer in go

Example use

import (
       os
       
       dot "github.com/zenground0/go-dot"
)

g := dot.NewGraph("MyGraph", os.Stdout)
var v1 dot.VertexDescription
v1.ID = "V1"
v1.Label = "Node1"
v1.Color = "blue2"
g.AddVertex(&v1)
var v2 dot.VertexDescription
v2.ID = "V2"
v2.Label = "Node2"
v2.Color = "blue1"
g.AddVertex(&v2)

g.AddEdge(v1, v2, true)
g.WriteDot()

output:

digraph MyGraph {
	V1 [label="Node1" color="blue2"]
	V2 [label="Node2" color="blue1"]
	V1 -> V2
}

Currently attribute support is barebones. Only attributes "label" and "color" are implemented. PRs welcome to extend this or add other features. Check the issues for proposals in flight, or this reference http://www.graphviz.org/pdf/dotguide.pdf for new ideas.
