This example shows the HTML5 SVG element rendering two circles: a default black circle and a red circle with a larger radius. The page contains static, hand-coded SVG markup embedded directly in the HTML, with no external JavaScript libraries. It demonstrates basic SVG shape creation through the `<circle>` element, specifying position and radius via the `cx`, `cy`, and `r` attributes, and styling through the `fill` attribute. The visualization is a minimal, non-interactive illustration of SVG's native vector graphics capabilities within a web page.
