A grid of eighteen randomly generated smiley faces, each rendered as a yellow SVG circle with black stroke, eyes, and an arc-shaped mouth. Built with React components and D3’s `arc` generator for mouth paths, the example uses `Math.random()` to vary stroke width, eye offset and radius, and mouth dimensions per face. D3’s `range` creates the face count, while the `FaceContainer` wraps all SVG elements in a translated group. The visualization demonstrates component-driven composition and reusability, with each face rendered independently via `ReactDOM.render`.
