This example demonstrates the foundational difference between HTML and SVG for data visualization, displaying a large "Hello HTML!" message styled with CSS. The code uses plain HTML elements and CSS font sizing to show how text renders in the browser, providing a minimal starting point for understanding DOM-based graphics. It references a React Starter template on VizHub but does not itself include React, JavaScript, or SVG elements. The page consists solely of a styled `<div>`, highlighting the basic structure needed before introducing SVG shapes or D3.js for data-driven rendering.
