A React component renders a classic smiley face as an SVG graphic, with a yellow circle for the head, black eyes, and an arched mouth. The visualization demonstrates how D3’s `arc` generator defines the mouth’s curved path, while the head and eyes are drawn as basic SVG circle elements. The code combines React’s declarative component structure with D3’s geometry utilities, using fixed pixel dimensions and coordinates to position each facial feature within a 960 by 500 viewport. The example highlights the integration of D3’s shape generation inside a React-rendered SVG.
