This example displays a grid of 32 randomly generated smiley faces, each with varying stroke widths, eye sizes and positions, and mouth dimensions. The grid is built by mapping over a range of indices, and each face is rendered as a composite of React components for the background circle, eyes, and mouth. The SVG output is generated using React’s declarative JSX syntax, while the mouth’s arc path is computed with D3’s `arc()` generator. All faces share the same SVG viewport and are positioned via a central transform.
