This example displays a simple yellow circle with a black outline and two smaller black circles positioned as eyes, forming a smiley face without a mouth. The visualization is rendered as static SVG shapes within an HTML page, using basic SVG elements such as `<circle>` with explicit `cx`, `cy`, `r`, `fill`, and `stroke` attributes. No JavaScript libraries or data sources are involved; the code relies solely on inline SVG markup and minimal CSS to hide page overflow.
