A grid of 18 identical cartoon faces fills the screen, each rendered with a gold background circle, black outline, two black eyes, and a curved mouth. The visualization demonstrates React component composition, where each face is built from reusable subcomponents like `FaceContainer`, `BackgroundCircle`, `Eyes`, and `Mouth`. The mouth shape is generated using `d3.arc()` from D3 v6, while all other shapes use plain SVG elements within a React rendering pipeline.
