This example displays a static yellow circle centered on a 960 by 500 SVG canvas, with a React-based root element positioned above it. The page loads React 16.7.0 and ReactDOM from unpkg, then uses `createRoot` from ReactDOM to mount a JavaScript component into the `#root` div. The SVG circle is rendered directly in the HTML markup, independent of the React component. The visualization demonstrates a minimal setup for combining React’s component model with raw SVG rendering in a single page.
