A stylized smiley face is rendered as an SVG, composed of a yellow circle, two black eyes, and a mouth drawn as a semicircular arc. The face is built through modular React components, with each part defined in its own file and composed together. The code uses React’s component structure and ES6 modules, while D3’s `arc` API generates the mouth path, and `d3.range` creates an array that is not used in the final display. The example demonstrates a clean separation of visual elements via reusable components, rendered with SVG in a React app.
