This example shows a centered message that reads “Hello HTML!” displayed at a large scale across the page. It demonstrates the simplest possible structure for a web-based visualization: a single HTML file containing inline CSS for styling and embedded JavaScript for interactivity. The code defines a `.message` class with a font-size of 13em and uses text-align to center the content. No external libraries or data sources are used; the page relies solely on native HTML, CSS, and JavaScript to render static text.
