This example renders the text “Hello HTML” centered on a plain white page using an enormous 13em font size. The code consists of a minimal `index.html` file that defines the page structure and styling with CSS, alongside an empty `index.js` file that contains no logic. It demonstrates the simplest possible setup for an HTML page without any external libraries, frameworks, or data sources, serving as a baseline template for more complex visualizations. The page’s static content and styling are declared entirely within the HTML document.
