This example demonstrates a minimal HTML page that renders the text “Hello HTML” in the browser, centered with a very large font size. It uses plain HTML and CSS, with the `text-align` property and a 13em `font-size` applied to the body. The page is a bare-bones starter template, containing no JavaScript libraries or data sources, and serves as a baseline for building more complex visualizations. It loads an external stylesheet for the React version, but this standalone file relies only on built-in browser rendering.
