This example renders a stylized smiley face in SVG using React and D3 v7. The face includes a brown-stroked orange circle, white eyes with black pupils, pink cheeks, brown ears and hair-like line segments, and a black arc mouth. D3’s `arc` generator creates the mouth and eye arcs, while React JSX defines the circular and elliptical shapes. All elements are positioned relative to the center of an 840×455 viewport.
