This example renders a yellow smiley face composed of SVG elements built with React components. It shows a central circle with a black stroke, two eyes positioned symmetrically, and an arc-shaped mouth created using the d3.arc() generator. The face is centered within an SVG container, with dimensions and offsets passed as props to control the radius, stroke width, eye placement, and mouth curvature. The visualization demonstrates reusable React components (Face, BackgroundCircle, Eyes, Mouth) and integrates D3’s arc function for path generation.
