This example demonstrates a foundational SVG circle element, showing how vector graphics render geometric primitives directly in the browser. It uses raw SVG markup embedded in an HTML file, with the `<circle>` tag specifying a center point and radius. The code relies on SVG's built-in XML-based syntax rather than a JavaScript library, with no external dependencies. The circle is displayed without styling, relying on the default black fill, while a CSS rule sets an unusually large font size for a hidden class, which does not affect the graphic.
