Let's make a face with d3.js
A face constructed from SVG shapes is assembled and animated using D3.js v3. The example demonstrates how common SVG elements—such as circles, ellipses, and paths—can be combined and manipulated through D3’s data-binding and selection methods. The code uses `d3.select` to append nodes, `d3.scale` for coordinate mapping, and `transition` to move facial features like eyes and a mouth. The embedded video shows the author building the face step-by-step, while the live page renders the static result in a full-screen SVG canvas.
