Smiley Face Part I
A yellow smiley face drawn as a single SVG circle with a black stroke centers itself on a 960-by-500 canvas using React’s JSX syntax and `ReactDOM.render`. The face’s position is calculated from `width / 2` for horizontal centering, while the radius and stroke-width are hardcoded values, producing a static, minimalist composition. Although commented-out code suggests planned eyes, the rendered output includes only the head circle. The visualization demonstrates basic SVG shape rendering within a React component tree.
