This example shows a stylized face built from D3.js SVG shapes within a React application. The face consists of a yellow circle for the head, black circles for eyes, and D3 arc paths for the mouth, nose, and eyelid-like accents, all positioned using SVG group transforms. The code uses the `arc` generator from D3 v6 to define the mouth, nose, and eye arcs, while React renders the SVG elements. A CSS class applies red fill to the eye arcs, creating a subtle color contrast against the black strokes.
