This example demonstrates the foundational SVG circle element, showing how to define basic vector graphics for web pages. The code creates a single red circle with explicit attributes for center coordinates (`cx`, `cy`) and radius (`r`). The circle is drawn directly inside an inline `<svg>` element within the HTML body, using the browser’s native SVG rendering. No external JavaScript libraries are used; the example relies purely on static markup with hardcoded pixel values (960 by 500 viewport, circle at 250,250 with a 50-pixel radius).
