This example displays a static HTML page with a large, centered message reading “Hello HTML!” styled at 13em font size. The page uses plain CSS for layout and styling, with no JavaScript libraries or data visualization frameworks involved. The entire visualization consists of a single text element rendered directly in the browser, demonstrating a minimal setup for a web page skeleton. The code includes a reference to a React Starter example but does not actually use React or any D3 APIs in the rendered output.
