SVG fundamental
This example demonstrates the foundational structure of an SVG-based web page, displaying a centered "Hello HTML!" message using CSS styling. The page’s core is a minimal HTML document that links a stylesheet and uses JavaScript as a scripting language, though the provided code only includes inline CSS and no external scripts. It serves as a bare-bones starting point for building more complex visualizations with SVG, relying on standard HTML tags and CSS properties like `font-size` and `text-align` to control text appearance. No data or rendering libraries are used; the code is purely static markup.
