This example shows a static SVG scene of a yellow circle with black outline and two smaller circles, alongside a React-rendered heading. The page loads React 18 and ReactDOM 17 via UMD scripts, then uses `ReactDOM.render` to insert JSX into a root div. The SVG circles are drawn directly in the HTML, with hardcoded coordinates and styles. The code demonstrates basic SVG markup combined with React’s declarative rendering, though the SVG elements are not generated through React components.
