This example shows a simple SVG face rendered as a grey circle on an HTML page. The code uses plain HTML and CSS, with the circle drawn via an SVG `<circle>` element that has a radius of 100. A minimal inline `style` attribute sets the page background, while the SVG itself is unstyled beyond the geometric definition. The demonstration highlights how basic SVG shapes can be embedded directly in HTML without additional libraries or JavaScript, serving as a starting point for interactive visualizations.
