This example demonstrates a minimal HTML page that renders the text “Hello HTML” in the center of the browser window using pure HTML and CSS. The page relies on a simple `<style>` block to set the body’s `text-align` to `center` and a large `13em` font size. No JavaScript libraries or data sources are involved; it serves as a basic template for starting HTML-based visualizations. The code uses standard HTML tags and global CSS properties, with no external dependencies or frameworks.
