This example shows a grid of 18 cartoon faces, each rendered with slightly randomized eye and mouth sizes, creating a playful sense of variety. It uses React components to compose the face from separate SVG shapes: a yellow background circle, two eyes, and an arc-based mouth. The code leverages D3’s `arc` API to generate the mouth path, and React’s `range` utility from D3 to create the array of faces. Rendering is done entirely in SVG within a React application.
