A smiling face is drawn as a static SVG graphic, composed of a yellow circle for the head and two smaller black circles for the eyes on a 960×500 canvas. The example demonstrates basic React setup with `ReactDOM` imported in `index.js`, while `index.html` directly renders SVG elements without using React components for the visualization. The page loads React 18.1.0 and ReactDOM from unpkg CDN, plus a `bundle.js` script, with minimal CSS hiding page margins and overflow.
