 Array of points ([x, y]) to triangulate, defaults to null. When not specified an array randomised points is generated filling the space. Points must be within the coordinate space defined by `width` and `height`. See [`examples/custom-points-example.html`](./examples/custom-points-example.html) for a demonstration of how this option can be used to generate circular trianglify patterns.
