This example displays a static, hand-coded SVG scene on an HTML page, featuring a large red circle with a black outline and two smaller black circles positioned within it. The page loads React 18.2.0 from a CDN and uses `ReactDOM.render` in `index.js` to inject a simple "Hello Jsx" heading into a separate root element, while the SVG is placed directly in the markup. The visualization relies on raw SVG elements, not React-generated drawing, and includes no interactive or data-driven behavior.
