SVG fundamentals
This example demonstrates a minimal HTML page that uses CSS for styling and JavaScript for basic interactivity, rendering a large “Hello HTML!” message centered on the screen. The code defines a `.message` class with a font size of 13em and text alignment, applied to a single div element. It serves as a bare-bones starter template, with no data visualization or external libraries, highlighting the fundamental roles of HTML structure, CSS presentation, and inline JavaScript in a web page.
