SVG Fundamentals
This example demonstrates the fundamental distinction between HTML and SVG rendering for data visualization. It presents a simple "Hello HTML!" message styled with CSS, serving as a baseline for understanding how web technologies handle graphical output. The code uses plain HTML elements with a CSS class for styling, and JavaScript is referenced but not yet implemented for any drawing logic. The example acts as a starting point for learning how to transition from HTML-based text display to more advanced SVG-based visualizations, highlighting the structural differences between these markup languages in a web browser context.
