This example renders a simple cartoon smiley face as a static SVG graphic. It uses React to define the component structure and D3’s `arc()` generator to create the mouth shape. The face consists of a yellow circle with a black stroke, two black eye circles positioned with fixed offsets, and a path built from an arc with specified inner and outer radii. All elements are centered within a 960×500 SVG viewport using a translated group, with hardcoded numeric values for dimensions and positioning.
