This example demonstrates the simplest possible visualization setup: a static HTML page that displays the text “Hello HTML” in large, centered type against a plain white background. The styling uses a CSS `style` block within the `index.html` file, setting the body’s `font-size` to 13em and `text-align` to center. No JavaScript libraries or rendering frameworks are involved, making this a pure HTML/CSS showcase. It serves as a minimal scaffold for understanding the basic structure of a web-based visualization before adding interactive or data-driven elements.
