This example displays a single phrase, “Hello HTML,” centered on a white page. It demonstrates the most basic web page setup using a plain HTML file with inline CSS styling. The code uses standard HTML tags like `<html>`, `<head>`, `<style>`, and `<body>` to structure the document, and a CSS rule sets the font size and text alignment. There is no data, library, or dynamic behavior involved; it is a minimal starting point for building more complex visualizations.
