This example displays the text "Hello HTML" centered on a plain white page, serving as a minimal demonstration of an HTML document rendered within a React-based visualization framework. The page is styled with a CSS rule that sets the body font size to ten em units and applies center text alignment. The underlying code consists solely of an HTML file with a single body element, making it a bare-bones starting point for browser-based visualizations. It does not incorporate any JavaScript data processing or rendering libraries.
