A grid of 18 smiling yellow faces fills the view, each with randomized eye sizes and a fixed mouth shape. The faces are rendered as SVG circles with black outlines, built from reusable React components for the background, eyes, and mouth. D3's arc generator creates the mouth path, while the React app maps over a d3.range to produce each face. The component props control geometry like eye offset and mouth radius, allowing variation across the grid.
