This example displays a single large "Hello HTML" message centered on a blank white page. It is a minimal demonstration of a static web page, using plain HTML and CSS within an `index.html` file. The page relies on the HTML `<style>` tag to set the body’s font size to 13em and center the text, showcasing how basic styling can be applied without JavaScript or external libraries. The rendering approach is entirely browser-native, with no data source or dynamic behavior present. It serves as a foundational template for starting new visualization projects, particularly as a contrast to React-based starters.
