This example shows a yellow smiley face rendered as a static SVG graphic. The face consists of three circles: a large yellow circle for the head and two smaller black circles for eyes, all positioned with explicit `cx`, `cy`, and `r` attributes. The rendering is pure SVG, embedded directly in the HTML page, and does not use the React framework for drawing. The page loads React and ReactDOM libraries via CDN, and `index.js` defines a simple React app that renders a heading, but the SVG markup is separate and static.
