A grid of smiley faces, each with a yellow circular head, black outline, eyes, and a mouth, repeats across the view. The example uses React to render SVG circles and paths defined in modular components. It leverages D3’s `arc` generator to shape the mouth and `range` to create eighteen faces, with randomized eye and mouth sizes via `Math.random()`. The `FaceContainer` translates the SVG origin to center each face.
