This example demonstrates the foundational structure of an SVG visualization, presenting a simple "Hello HTML!" message centered on the page. It shows how HTML, CSS, and JavaScript combine to create a basic, styled text display. The code uses plain HTML elements with a CSS class to control font-size and text alignment, without relying on any JavaScript libraries or data sources. It serves as a minimal starting point for understanding web-based visualization setup, contrasting with more complex React-based projects.
