This example shows a single line of large, centered text reading “Hello HTML!” inside a minimal web page. It demonstrates the foundational structure of an HTML document with embedded CSS styling and no JavaScript logic. The code uses plain HTML elements like `<div>` and `<style>` tags to define the visual presentation, while the body contains the static content. It serves as a basic starter template for web-based visualization projects, though it does not include any data, interactivity, or external libraries.
