@graphty/layout v1.0.1

Layout.js

Layout.js is a JavaScript library for node positioning in graphs. It is a JavaScript port of the layout algorithms found in the Python NetworkX library.

Features

The library offers various graph layout algorithms, including:

• Random Layout
• Circular Layout
• Shell Layout
• Spring Layout (Fruchterman-Reingold)
• Spectral Layout
• Spiral Layout
• Bipartite Layout
• Multipartite Layout
• BFS Layout
• Planar Layout
• Kamada-Kawai Layout
• ForceAtlas2 Layout
• ARF Layout (Attractive and Repulsive Forces)

How to Use

Import the library into your JavaScript project:

import {
  randomLayout,
  circularLayout,
  springLayout
  // other layout functions...
} from './layout.js'

Usage example:

// Create a graph (data structure with nodes() and edges())
const graph = {
  nodes: () => [0, 1, 2, 3],
  edges: () => [
    [0, 1],
    [1, 2],
    [2, 3],
    [3, 0]
  ]
}

// Apply a layout
const positions = circularLayout(graph)

// positions will be an object with x,y coordinates for each node
// { 0: [1, 0], 1: [0, 1], 2: [-1, 0], 3: [0, -1] }
