Usage instructions

Download the library:

• via npm: npm install cytoscape-supportimages,
• via bower: bower install cytoscape-supportimages, 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 supportimages = require('cytoscape-supportimages');

supportimages( cytoscape ); // register extension

AMD:

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

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