This visualization displays a grid of eighteen randomly generated smiley faces, each with slightly varying eye positions, radii, stroke widths, and mouth dimensions. Built with React and D3 v5, the faces are composed from modular components like BackgroundCircle, Eyes, and Mouth, with the mouth drawn using the d3.arc path generator. The code maps over a range array to render each face as an SVG group, using React to orchestrate the reusable face components and D3 for shape generation.
