cytoscape-cytoscape-ngraph.forcelayout

Description

cytoscape-ngraph.forcelayout

Dependencies

  • Cytoscape.js >=x.y.z

Usage instructions

Download the library:

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

require() the library as appropriate for your project:

CommonJS:

var cytoscape = require('cytoscape');
var cyforcelayout = require('cytoscape-ngraph.forcelayout');

cyforcelayout( cytoscape ); // register extension

AMD:

require(['cytoscape', 'cytoscape-ngraph.forcelayout'], function( cytoscape, cyforcelayout ){
  cyforcelayout( cytoscape ); // register extension
});

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

Please briefly describe your API here:
