This example shows a minimal HTML page containing a single SVG circle with a radius of 100 units. The page uses a bare-bones HTML structure with an embedded `<svg>` element, demonstrating how to include vector graphics directly in an HTML document. The circle is rendered without any styling or interactive behavior, highlighting the basic relationship between HTML markup and SVG content. The code relies on native HTML and SVG support in the browser rather than external JavaScript libraries, making it a foundational demonstration of inline SVG rendering.
