This example renders a classic smiley face as a static SVG illustration. The face consists of a yellow circle with a black stroke, two black eyes, and a mouth drawn as an arc with a thick stroke width. Built with React for component structure and D3’s `arc` generator for the mouth shape, the visualization uses fixed dimensions (960×500) and centers all elements within a single SVG `<g>` group. The code defines reusable components like `BackgroundCircle` and positions the eyes and mouth using explicit pixel offsets and radius values.
