Using D3 v7's `arc` generator, this React-based example constructs a stylized cartoon face composed of modular SVG components for the background circle, eyes, mouth, and teeth. The face is drawn within a centered SVG group using React functional components with configurable props like radius, offsets, and widths. The teeth are rendered as a filled arc with black dividing lines, while the mouth uses an arc path. The code demonstrates component composition and reusable D3 shape generators within a React rendering framework.
