This example shows a static smiley face composed of three SVG circles: a large yellow circle for the face and two smaller black circles for the eyes. The React library renders the outer SVG container, while the circles are defined directly in the markup with fixed positions and radii. A background YouTube video is embedded in the README, but the face itself uses no interactive behavior or data-driven elements. The page loads React and ReactDOM from a CDN, though the main `index.js` file contains an unfinished React component.
