This example displays a static web page with the message "Hello HTML!" centered on the screen. The code uses raw HTML, CSS, and JavaScript, with the `index.html` file linking to external `styles.css` and `index.js` files. The CSS class `.message` sets the font size to 12em, while the JavaScript file simply logs "hello world" to the console. It demonstrates a minimal HTML/CSS layout with a basic script, without any data visualization or interactive features.
