Fork of Smiley face part 1 cooler face
This example shows a stylized smiley face rendered as an SVG using React and D3. The face consists of a yellow background circle, two eyes, and a mouth drawn with an arc generator from D3. The components are modular, with separate React components for the face, eyes, mouth, and background circle, all composed within a face container that applies a transform to center the graphic. The mouth uses `d3.arc()` with specified inner and outer radii and angles to create a curved smile shape.
