cytoscape-d3-force

Description

d3-force for cytoscape.js (demo)(demo-bigdata)

Dependencies

  • Cytoscape.js ^3.2.0

Usage instructions

Download the library:

  • via npm: npm install cytoscape-d3-force,
  • via bower: bower install cytoscape-d3-force, or
  • via direct download in the repository (probably from a tag).

Import the library as appropriate for your project:

ES import:

import cytoscape from 'cytoscape';
import d3Force from 'cytoscape-d3-force';

cytoscape.use( d3Force );

CommonJS require:

let cytoscape = require('cytoscape');
let d3Force = require('cytoscape-d3-force');

cytoscape.use( d3Force ); // register extension

AMD:

require(['cytoscape', 'cytoscape-d3-force'], function( cytoscape, d3Force ){
  d3Force( cytoscape ); // register extension
});

Plain HTML/JS has the extension registered for you automatically, because no require() is needed.

API

{
  animate: true, // whether to show the layout as it's running; special 'end' value makes the layout animate like a discrete layout
  maxIterations: 0, // max iterations before the layout will bail out
  maxSimulationTime: 0, // max length in ms to run the layout
  ungrabifyWhileSimulating: false, // so you can't drag nodes during layout
  fixedAfterDragging: false, // fixed node after dragging
  fit: false, // on every layout reposition of nodes, fit the viewport
  padding: 30, // padding around the simulation
  boundingBox: undefined, // constrain layout bounds; { x1, y1, x2, y2 } or { x1, y1, w, h }
  /**d3-force API**/
  alpha: 1, // sets the current alpha to the specified number in the range [0,1]
  alphaMin: 0.001, // sets the minimum alpha to the specified number in the range [0,1]
  alphaDecay: 1 - Math.pow(0.001, 1 / 300), // sets the alpha decay rate to the specified number in the range [0,1]
  alphaTarget: 0, // sets the current target alpha to the specified number in the range [0,1]
  velocityDecay: 0.4, // sets the velocity decay factor to the specified number in the range [0,1]
  collideRadius: 1, // sets the radius accessor to the specified number or function
  collideStrength: 0.7, // sets the force strength to the specified number in the range [0,1]
  collideIterations: 1, // sets the number of iterations per application to the specified number
  linkId: function id(d) {
    return d.index;
  }, // sets the node id accessor to the specified function
  linkDistance: 30, // sets the distance accessor to the specified number or function
  linkStrength: function strength(link) {
    return 1 / Math.min(count(link.source), count(link.target));
  }, // sets the strength accessor to the specified number or function
  linkIterations: 1, // sets the number of iterations per application to the specified number
  manyBodyStrength: -30, // sets the strength accessor to the specified number or function
  manyBodyTheta: 0.9, // sets the Barnes–Hut approximation criterion to the specified number
  manyBodyDistanceMin: 1, // sets the minimum distance between nodes over which this force is considered
  manyBodyDistanceMax: Infinity, // sets the maximum distance between nodes over which this force is considered
  xStrength: 0.1, // sets the strength accessor to the specified number or function
  xX: 0, // sets the x-coordinate accessor to the specified number or function
  yStrength: 0.1, // sets the strength accessor to the specified number or function
  yY: 0, // sets the y-coordinate accessor to the specified number or function
  radialStrength: 0.1, // sets the strength accessor to the specified number or function
  radialRadius: [radius]// sets the circle radius to the specified number or function
  radialX: 0, // sets the x-coordinate of the circle center to the specified number
  radialY: 0, // sets the y-coordinate of the circle center to the specified number
  // layout event callbacks
  ready: function(){}, // on layoutready
  stop: function(){}, // on layoutstop
  tick: function(progress) {}, // on every iteration
  // positioning options
  randomize: false, // use random node positions at beginning of layout
  // infinite layout options
  infinite: false // overrides all other options for a forces-all-the-time mode
}

Build targets

  • npm run test : Run Mocha tests in ./test
  • npm run build : Build ./src/** into cytoscape-d3-force.js
  • npm run watch : Automatically build on changes with live reloading (N.b. you must already have an HTTP server running)
  • npm run dev : Automatically build on changes with live reloading with webpack dev server
  • npm run lint : Run eslint on the source

N.b. all builds use babel, so modern ES features can be used in the src.

Publishing instructions

This project is set up to automatically be published to npm and bower. To publish:

  1. Build the extension : npm run build:release
  2. Commit the build : git commit -am "Build for release"
  3. Bump the version number and tag: npm version major|minor|patch
  4. Push to origin: git push && git push --tags
  5. Publish to npm: npm publish .
  6. If publishing to bower for the first time, you'll need to run bower register cytoscape-d3-force https://github.com/shichuanpo/cytoscape.js-d3-force.git
  7. Make a new release for Zenodo.
