This example shows a minimal HTML page displaying the static text “Hello HTML!” in large, left-aligned type styled with CSS. The page is structured with a single `div` element inside `body`, and uses a style block to set the font size to 13 em. It demonstrates the foundational use of plain HTML for markup and CSS for presentation, with no JavaScript or data visualization involved. The code serves as a bare-bones starting point for building web-based visualizations, relying only on native browser rendering.
