This example renders a static HTML page with a large, centered message reading “Hello HTML!”. It uses plain HTML, CSS, and JavaScript: the `styles.css` file styles the message with a font size of 12em and text alignment, while `index.js` contains a single `console.log` call. No data source or interactive visualization is present, and the page does not use any external libraries such as D3 or Three.js. The demonstration shows the minimal structure of a web-based starter template.
