A smiley face is drawn as three static SVG circles within a React application. The code creates a yellow head with black stroke and two dark eye circles, but no mouth is defined. The implementation uses React 16.9 via UMD builds from unpkg, rendering directly to the DOM through `ReactDOM` and JSX-like elements, though the HTML also includes a pre-rendered SVG fallback. The example demonstrates minimal SVG integration with React without any interactive behavior or data-driven features.
