This example displays a static webpage with the message “Hello HTML!” centered and styled with large text. It serves as a minimal starter template, showing the foundational structure of an HTML page that integrates CSS for styling and JavaScript for potential interactivity. The code uses plain HTML elements, a `<style>` block for CSS rules, and an empty `index.js` file. No data visualization is present; it only demonstrates the basic layout and styling approach for beginning a project.
