Smiley Face Part I
This example renders a static smiley face using raw SVG elements inside a React application. The visualization shows a yellow circle with a black outline for the face, plus two smaller unfilled circles positioned as eyes, all defined directly in the markup. The code loads React and ReactDOM from CDN and attempts to render a simple JSX heading into a root div, while the smiley face is drawn separately via an inline `<svg>` tag. It demonstrates basic SVG drawing without any interaction or data-driven mapping.
