The gallery displays a grid of eighteen randomly generated smiley faces, each rendered as a yellow SVG circle with black outlines, eyes, and a curved mouth. Built with React and D3 v7, the Face component composes BackgroundCircle, Eyes, and Mouth subcomponents, using D3’s `arc()` generator to create the mouth’s path. Faces vary in stroke width, eye offset, eye radius, mouth radius, and mouth width via JavaScript `Math.random()` calls. The SVG container centers each face using a transform, producing a playful, varied set of cartoon-like avatars.
