This example renders a yellow smiley face as a static SVG graphic using React and D3. The code constructs the face from a large circle for the head, two smaller circles for the eyes, and a D3 `arc` path for the mouth, all positioned relative to the center via a `g` transform. The `BackgroundCircle` React component draws the head with a yellow fill and black stroke, with the `strokeWidth` and radii defined as constants. The face is centered within a 960 by 500 viewport using D3’s `arc` helper to create the semi-circular mouth.
