This example demonstrates a modular React application that renders a smiley face using SVG primitives. The code splits components into separate files—BackgroundCircle, Eyes, and Mouth—each importing React and leveraging ES6 modules for organization. It uses React Fragments in the Eyes component to return multiple circles without extra DOM nodes. The visualization computes a d3.arc path for the mouth shape, while the overall layout is positioned with an SVG transform. The face is drawn with a yellow background circle, black stroke, two eyes, and an arc-based mouth on a 960×500 canvas.
