Hello HTML
This example renders a static circular shape within an inline `<svg>` element on a bare HTML page. It demonstrates a minimal setup for styling SVG elements using CSS, specifically targeting a circle class with an `r` attribute. The page combines HTML structure, embedded CSS rules, and JavaScript support, though no scripted interaction or data processing occurs in the provided code. It serves as a starting point for building interactive visualizations with the React framework, as referenced in the linked starter project.
