A yellow smiley face rendered with SVG appears at the center of a 960×500 canvas, showing a circle for the head, two black eyes at fixed offsets, and a semi-circular mouth drawn as an arc. The example uses React 18 to manage the component structure while leveraging D3 v7’s `arc` generator to create the mouth path with inner and outer radii. All shapes are positioned via a translated `<g>` group, with stroke styling applied directly to SVG circle elements.
