A fork of the Smiley Face Part II example uses React to render a responsive, full-window SVG smiley face. The face’s position and size are calculated from the browser viewport’s width and height, with its center, eye offsets, and mouth radius all derived from those dimensions. The SVG output is generated using React’s declarative syntax, and the `ReactDOM.render` API places the resulting component into the page’s root element. The code defines all geometry—such as the face’s yellow fill, black stroke, eye circles, and mouth arc—inline within the React component’s return value, though the final rendering relies on the bundled JavaScript in `bundle.js`.
