A single SVG circle is drawn at the center of an otherwise minimal HTML page. The circle uses no explicit dimensions or styling, so it relies on the browser’s default SVG rendering. The page includes an embedded YouTube iframe and a README linking to Wikipedia’s HTML article, but the core graphic is produced directly via the inline `<svg>` and `<circle>` elements. No JavaScript or external libraries are used; the example simply demonstrates the most basic SVG shape within a valid HTML document.
