This example displays the text “Hello HTML” at a massive font size, centered on a plain white page. It demonstrates the bare minimum structure of an HTML document, using a `style` tag to set the `body` element’s `text-align` to center and `font-size` to 13em. The page contains no external libraries or data sources, relying solely on static HTML and CSS to render its content. It serves as a minimal starting point for web-based visualizations.
