This example displays a grid of eighteen randomly generated smiley faces, each rendered as an independent React component. The faces vary in stroke width, eye position and radius, and mouth thickness and curvature. The visualization uses React with D3’s `arc` generator to create the mouth paths, while SVG circles compose the background and eyes. All faces share the same center point within a 160×160 viewport, and the code relies on `Math.random()` to produce each face’s unique attributes.
