This example shows a classic smiley face rendered as a static SVG graphic, composed of a yellow circular background, two black eyes, and a black arc-shaped mouth. The visualization is built using React components for each facial feature, with D3’s `arc` API generating the mouth’s path geometry. The code defines specific dimensions and offsets for the features, centered within a 960 by 500 pixel viewport, and renders the final composition through a React DOM call.
