This smiley face visualization renders a static, SVG-based cartoon face using React components and D3’s `arc` generator for the mouth. The background circle, eyes, and mouth are positioned via a translated coordinate system, with constants defining radii and offsets. Built with React 16.9 and D3 v5, it uses three reusable functional components—`BackgroundCircle`, `Eyes`, and `Mouth`—to compose the final shape, demonstrating a modular approach to SVG drawing within a React framework.
