This example presents a minimal single-page visualization that displays the text “Hello HTML” centered on a white background. It demonstrates the foundational structure of an HTML document using a basic `<!DOCTYPE html>` declaration, a `<head>` section with a title and inline CSS styling, and a `<body>` containing the text. The code is a pure HTML/CSS implementation, with no JavaScript, data sources, or charting libraries involved. It serves as a starting point for building more complex web-based visualizations.
