This example displays a static, centered message reading "Hello HTML!" in extremely large, bold text. It demonstrates a minimal setup for a web page using standard HTML and CSS, with the styling defined in a `<style>` block to control font size and alignment. The page is a bare-bones starter template, with the message wrapped in a `<div>` element with the class "message". It does not include any JavaScript or external libraries, serving as a foundational example for building more complex visualizations or applications.
