A grid of eighteen tiny, simple faces, each with a yellow circular head, black outline, two eyes, and a curved mouth, fills the canvas. The faces vary slightly in stroke thickness, eye position and size, and mouth dimensions, creating subtle differences across the repeated pattern. Built with React and rendered as SVG, the example uses D3’s `arc` generator for the mouth paths and generates random parameter values via `Math.random` for each face. The components are modular, with separate files for the background, eyes, mouth, and container.
