SVG Fundamentals
This example demonstrates the foundational relationship between HTML, CSS, and JavaScript in a web page, displaying a large “Hello HTML!” message centered via CSS. The code uses a plain HTML `<div>` with a CSS class for styling and font sizing, with no external libraries or data sources. It serves as a minimal starting point for understanding DOM structure and styling before introducing SVG or React-based visualization patterns, as referenced in the accompanying React Starter link.
