This example renders a classic smiley face using React and SVG. A yellow circle with a black outline forms the head, while two smaller filled circles serve as eyes; the mouth is not implemented in the visible markup. The code loads React and ReactDOM from unpkg CDN and relies on a separate `bundle.js` for application logic. The SVG canvas is 960 by 500 pixels, with the head centered and eyes positioned to the left and right. The rendering approach is declarative, using SVG circle elements directly in the HTML file.
