The gallery displays a grid of 18 identical, cartoonish yellow faces with black outlines, each generated with randomized facial feature parameters. Built with React and rendered as SVG, the example uses D3’s `arc` generator to construct the mouth shape, while all other components—the background circle, eyes, and face container—are hand-coded React components. Each face’s stroke width, eye offset, eye radius, and mouth dimensions vary randomly, demonstrating how component-based composition with D3 utilities can produce varied visual output.
