This example is a minimal HTML page that renders a single SVG circle. It demonstrates the foundational structure of an HTML document and the use of inline SVG markup to display a simple graphic element. The page's source code shows a basic `<!DOCTYPE html>` declaration, a `<head>` section with a title, and a `<body>` containing an `<svg>` element with a `<circle>` tag. The visualization solely relies on the browser's native rendering of the SVG, with no external libraries or additional styling.
