This example displays a grid of 18 randomly generated cartoon faces, each with yellow circular backgrounds, black outline strokes, eyes, and mouths. The code decomposes the face into separate React components—FaceContainer, BackgroundCircle, Eyes, and Mouth—to manage complexity. It uses React for component structure, D3’s arc generator for mouth shapes, and renders SVG elements. Each face’s dimensions and features (stroke width, eye offset, mouth radius) vary randomly, creating a diverse collection.
