A yellow smiley face rendered as an SVG, with a black circular outline, a pair of eyes, and a mouth. The face is centered within a 960 by 500 pixel viewport, with the head diameter determined by the height. Built with React, the component uses JSX to define three circle elements for the face outline and eyes, while the mouth remains as a commented-out placeholder. The code relies on React 18 and ReactDOM to mount the component into the page's root element.
