dot

dot is a Go package that provides support for working with the DOT language, which is used for describing graphs in Graphviz.

Features

• Create and manipulate graph structures
• Add nodes, edges, and subgraphs
• Set attributes for graphs, nodes, and edges
• Generate DOT language output
• Import and export graphs in DOT and JSON formats
• Graph analysis and algorithms (e.g., topological sort, shortest path)
• Graph visualization helpers (PNG and SVG output)

Installation

To install the dot package, use the following command:

go install github.com/tmc/dot@latest

Usage

Here's a simple example of how to use the dot package:

package main

import (
    "fmt"
    "github.com/tmc/dot"
)

func main() {
    g := dot.NewGraph("Example")
    g.Set("label", "This is an example graph")

    n1 := dot.NewNode("Node1")
    n1.Set("shape", "box")
    n2 := dot.NewNode("Node2")
    n2.Set("color", "red")

    g.AddNode(n1)
    g.AddNode(n2)

    e := dot.NewEdge(n1, n2)
    e.Set("label", "connects to")
    g.AddEdge(e)

    fmt.Println(g.String())
}

This will output the DOT language representation of the graph.
