A yellow cartoon face with black-outlined circular eyes and a curved mouth is rendered as an SVG using React components. The face is assembled from reusable parts: a background circle, two eyes, and a mouth, all positioned within a translated SVG group. The mouth’s arc is generated with the D3 `arc` generator, using specified inner and outer radii and start and end angles. The example demonstrates composing a simple visualization from modular React elements and D3 geometry.
