This example displays a simple, static smiley face composed of three SVG circles: a large yellow outline for the head and two smaller black circles for the eyes. The geometry is hardcoded directly in the markup within `index.html`, while a separate React component in `index.js` renders a trivial heading using `ReactDOM.render`. The visualization demonstrates basic SVG shape rendering alongside a minimal React setup, with the face serving as a backdrop rather than an interactive or data-driven graphic.
