Issue running examples

[bxuserx]

Cloned the latest, and tried to run the example. Added the CDNs, installed the bower folder in the directory, but I get the following errors:

Uncaught TypeError: aquarelle.addEventListener is not a function at index.html:139:15

Aquarelle.js:103 Uncaught TypeError: d3.geom.contour is not a function
at Aquarelle.drawMaskImage (Aquarelle.js:103:35)
at Image.Aquarelle.self.mask.img.onload (Aquarelle.js:24:22)

The problem in examples/index.html is here:

var aquarelle = new Aquarelle(image, 'img/mask.png', {
    autoplay: true,
    loop: true
});

aquarelle.addEventListener('created', function() {
    var canvas = this.getCanvas();
    canvas.removeAttribute('style');
    image.parentNode.insertBefore(canvas, image.nextSibling);
    image.parentNode.removeChild(image);
});

Using VSCODE Go-Live, macos, installed bower with brew. Thoughts? Thanks for looking!
