A static smiley face rendered as a single SVG with three circles: a large yellow face and two black eyes. The code uses React 16.9 and ReactDOM directly in an HTML file, but the SVG markup is hard-coded rather than generated by components. Head and eye positions are fixed numbers (e.g., cx="480", cy="250", r="245"), with no interactivity or animation. This is a minimal example showing basic SVG shapes inside a React document, where index.js merely logs the React object to the console.
