This example shows a yellow smiley face rendered five times in a row, each with identical parameters for its circular head, eyes, and mouth. The face is built from reusable React components, including a background circle, eyes, and a mouth, all composed within a scalable SVG container. The mouth uses the d3 `arc` API to generate a curved path, while the head and eyes are simple SVG circles with computed offsets. The entire composition is positioned and scaled using React and rendered through ReactDOM.
