This example uses React and D3 to render a stylized smiley face as an SVG graphic. The face is composed of a yellow circle with a black stroke, two black eyes, and a mouth drawn using the D3 `arc` generator with specified inner and outer radii and angles. The `arc` path is generated with `d3.arc()`, while React manages the SVG elements and D3 v6 provides the arc calculation. The visualization demonstrates a simple, static data-free composition with hardcoded dimensions and coordinates.
