A grid of 24 smiley faces, each rendered with a yellow circular background, black-outlined stroke, two eyes, and an arc-shaped mouth. The faces are generated by mapping over an array from the `d3.range` function, with random eye radii producing slight variations. Built with React components and D3’s `arc` generator, the SVG is transformed with a 30-degree rotation in `FaceContainer`, using `d3.v6` and React 17.
