SVG Intro
A bare-bones HTML document serves as a minimal demonstration of web fundamentals, displaying a single heading that reads "Hello HTML!" within a styled message container. The example uses no JavaScript libraries or data sources, relying solely on static markup and default browser rendering. It illustrates the absolute simplest starting point for a web-based visualization project, with the HTML structure defining content and the page ready for CSS and JavaScript to be added incrementally. This serves as a baseline reference for building more complex interactive visualizations.
