This example builds an animated face from scratch using D3.js v5 and SVG. It shows how basic geometric elements can be combined into a playful character, with each facial feature positioned and styled through D3’s data-binding and attribute manipulation. The code uses `d3.select` to target the SVG container and appends shapes like circles and paths, while `d3.forceSimulation` is not present; instead, simple static coordinates and CSS transitions animate the features. The face appears centered on a 960×500 canvas, with the stylesheet hiding page margins for a clean presentation.
