SVG Fundmental
This example shows a single SVG circle rendered at the center of a small canvas, demonstrating the basic structure of an HTML page that embeds SVG directly in markup. The circle is defined with `cx`, `cy`, and `r` attributes inside an `<svg>` element, using no external libraries. Instead, it relies solely on native SVG and CSS for styling, providing a minimal starting point for understanding vector graphics in the browser. The page contains no JavaScript logic, focusing purely on static SVG rendering within an HTML document.
