This example displays a centered greeting, “Hello HTML!”, styled with a 13em font size. It demonstrates a minimal HTML page that combines inline CSS for layout and JavaScript-ready structure. The implementation uses plain HTML `<div>` and `<style>` tags, with no external libraries or data sources. The rendering relies entirely on the browser’s default CSS engine to apply the large, center-aligned text style, making it a basic starting point for exploring web-based visualization setup without additional frameworks.
