A yellow circle with a thick black outline forms the head of a smiley face, accompanied by two smaller unfilled circles positioned as eyes. The visualization is a static, hand-coded SVG scene rendered directly in an HTML document. It uses the native SVG `<circle>` elements within an inline `<svg>` tag, with explicit `cx`, `cy`, `r`, `fill`, and `stroke` attributes to define geometry and styling. No external data or JavaScript libraries are involved; the rendering relies purely on SVG markup and CSS body styling.
