SVG Fundamentals
This example presents a minimal SVG circle rendered directly in an HTML page, demonstrating the fundamentals of Scalable Vector Graphics. The page contains no external libraries or frameworks, relying solely on native SVG elements and the browser's default styling. A single `<circle>` element is positioned with `cx`, `cy`, and `r` attributes, illustrating how geometric shapes are defined without CSS or JavaScript. The rendering approach uses the browser's built-in SVG engine, making it a bare-bones starting point for understanding vector graphics before incorporating React or other tools.
