This example demonstrates a minimal React application that renders a single centered message using JSX. It loads React 18.2.0 and ReactDOM from unpkg CDN, with the root component mounted into a `div#root` element. The page includes basic styling via CSS, setting a large font size for the message and hiding overflow with a zero margin. The JavaScript entry point simply logs the React object to the console, while the bundled output is referenced from the HTML file. No data sources or complex visualizations are involved; the focus is on a bare-bones setup for React-based web development.
