Built with React and D3 v7, this example renders a cartoon face as an SVG composed of reusable components. A yellow background circle, two black-outlined eyes, and a D3-generated arc path for the mouth are positioned within a transformed `<g>` container. The `Face` component receives numeric props for dimensions, offsets, and stroke widths, and the face is centered on a 960 by 500 canvas using static coordinate calculations.
