A grid of eighteen yellow smiley faces in a React and SVG composition, each generated with randomized eye sizes using `Math.random()`. The faces are assembled from modular React components—`BackgroundCircle`, `Eyes`, `Mouth`, and `FaceContainer`—that render SVG elements. The mouth uses `d3.arc` to create a half-circle path, while the background circle and eyes are plain SVG circles. Each face is independently styled with fixed dimensions and offsets, producing a uniform yet subtly varied pattern across the display.
