This fork of Smiley Face Part II renders a yellow smiley face using React and SVG, sized to fill the browser window. The face, drawn with circles for the head, eyes, and mouth, is centered on the page. The code uses React’s `ReactDOM.render` to inject the SVG into the DOM and D3’s `arc` import, though the actual drawing relies on basic SVG shape elements. The implementation adapts the original example by computing coordinates dynamically from `window.innerWidth` and `window.innerHeight`, and positions the features relative to the center.
