A yellow smiley face drawn with SVG circles and an arc for the mouth, centered on a 960×500 canvas. The React components compose the face from a background circle, two eyes, and a mouth, with all positions and sizes passed as props. D3’s `arc` generator creates the mouth path using an inner and outer radius with fixed start and end angles. The `FaceContainer` wraps the elements in a translated SVG group, and the example is rendered with React 18 and D3 v7.
