 * Test method borrowed from d3 : https://github.com/d3/d3-selection/blob/v3.0.0/test/jsdom.js
 *
 * Fools d3 into thinking it's working in a browser with a real DOM.
 *
 * The DOM is actually an instance of JSDom with monkey-patches for DOM methods that require a
 * rendering engine.
 *
 * The resulting environment is capable of rendering SVGs with the caveat that layouts are
 * completely screwed.
 *
 * This makes it possible to make structural tests instead of mocking everything.
