This example demonstrates a minimal web page that uses HTML, CSS, and JavaScript to display a centered message. The page contains a single `<div>` element with the text “Hello HTML!”, styled with a large font size and horizontal alignment via a CSS class. The code uses plain HTML structure and CSS styling rules, with no external libraries or frameworks. It serves as a bare-bones template for rendering static content in the browser, intended as a starting point for more complex visualizations or interactive applications.
