This example demonstrates a minimal interactive-free SVG graphic: a single large circle rendered inside an SVG element. The page uses raw CSS for layout and styling, with the `body` margin removed and overflow hidden. The circle is created declaratively in the markup with a radius of 400, and the stylesheet includes a `.highlighted` class that turns text red, though it is not applied to the circle. The implementation relies on plain HTML, CSS, and inline SVG, without any JavaScript libraries or external data sources.
