This example shows a minimal HTML page that displays the text "Hello HTML" at a very large font size in the center of the browser window. The page consists of plain HTML with embedded CSS, using the `text-align` property for horizontal centering and a `font-size` of 13em to scale the text. No JavaScript libraries or frameworks are used; it relies entirely on native HTML and CSS rendering to demonstrate a bare-bones starting point for web-based visualizations.
