A smiling face rendered as a yellow circle with black eyes and an open mouth, drawn entirely with SVG shapes. The React component builds the graphic using D3's arc generator to create the mouth path, while circles position the face and eyes relative to the center of a 960 by 500 viewport. D3 v5 supplies the arc function, and React 16.9 handles rendering into the root element, with static styling for fill, stroke, and dimensions.
