A grid of twenty small, static smiley faces renders in an SVG canvas. Each face consists of a yellow background circle with a black stroke, two circular eyes, and a mouth drawn with d3’s `arc` generator, creating a half-circle from inner and outer radii. The React application maps over a `d3.range(20)` array to produce these faces, with randomized eye radii for slight variation. The SVG is structured through reusable React components, including `FaceContainer` for the coordinate transform and `BackgroundCircle` for the base shape.
