This example displays the text “Hello HTML” centered on a plain white page, with the styling set to a very large font size. It demonstrates the most basic setup for a web-based visualization, using standard HTML and embedded CSS within a single `index.html` file. The styling is applied directly in the document’s `<head>` using a `<style>` block, and the content is placed in the body. It serves as a minimal starting point for projects that do not require additional libraries or frameworks.
