Welcome

Warning

this package is a WIP and will introduce breaking changes while on major version zero.

Dot is a lightweight, pure golang graphviz-compatible dot language implementation focused on generating dot/gv files that Graphviz can then convert into any of its output formats supported (e.g. png, jpeg, svg, pdf).

Dot provides both interfaces and ready-to-use concrete types that represent dot language resources - namely Graphs, Nodes and Edges, plus all attributes.

This package was inspired/initially forked from emicklei/dot, but has too many breaking changes compared to the original - namely interface usage and other distinct design decisions - so it seemed better to maintain it separately. If you need a simpler, no-brainy option, use emicklei's dot package.

Installation

Fetch the package using go

go get -u github.com/wwmoraes/dot

package main

import (
  "os"
  "github.com/wwmoraes/dot"
)

func main() {

  graph.Node("n1").SetAttributeString("label", "hello dot!")

  fd, _ := os.Create("sample.dot")
  defer fd.Close()

  graph.WriteTo(fd)
}
