This example demonstrates how to embed an SVG circle within a minimal HTML5 document. A single circle with a radius of 200 pixels is drawn inside an SVG element with a width of 960 and height of 500. The page uses basic CSS to remove margins and hide overflow, while the SVG circle does not include any fill or stroke attributes, so it renders as a default black shape. The code relies solely on standard HTML, CSS, and the native SVG API, with no external libraries or data sources.
