A yellow smiley face is drawn as a static SVG graphic centered on the page, with black-outlined circular eyes, a black arc for the mouth, and a smaller arc for the nose. Built with React and D3 v7, the code defines shapes using D3’s `arc` generator for the mouth and nose paths, while the face and eyes are plain SVG `<circle>` elements. The rendering leverages React’s declarative JSX to output the SVG structure, with coordinates and dimensions computed from fixed variables.
