A grid of fifteen small, abstract faces, each with a yellow circular head, black outline, two eyes, and a smile-shaped mouth, demonstrates randomized facial feature placement within fixed SVG viewports. The React application renders each face using a composite of SVG primitives, with positional and dimensional parameters like eye offset, radius, and mouth curvature generated via `Math.random()`. The mouth shape is constructed using the D3 arc generator from the `d3` library, while the overall layout is produced with D3’s `range` function to map over a 5×3 array, yielding varied expressions across the collection.
