This example displays a yellow circle with a black outline and a single black dot at its center, resembling a simple face. The circle is drawn using the SVG `circle` element, with fixed `cx`, `cy`, and `r` attributes, and is rendered inside an inline `<svg>` block. The page uses HTML and CSS to define the layout, setting the body margin to zero and hiding overflow. No JavaScript or external libraries are involved; the visualization relies solely on static SVG markup.
