A single red circle is drawn inside an SVG element on a bare-bones HTML page, demonstrating the foundational relationship between CSS, JavaScript, and SVG rendering. The circle is positioned at coordinates (50, 50) with a radius of 40, and its fill color is set to red via a CSS rule that targets all SVG elements. This example uses plain HTML and inline CSS, with no JavaScript or external libraries, serving as a minimal showcase of static vector graphics in the browser.
