This example shows a static SVG smiley face drawn with two yellow and black circles, a nose, and a mouth, rendered alongside a React “Hello World” heading. The SVG uses hard-coded circle elements with fill, stroke, and stroke-width attributes to create the face. The page loads React 17 and ReactDOM from a CDN, while `index.js` uses `ReactDOM.render` to mount a simple `App` component. The SVG is placed directly in the HTML body rather than being generated by React.
