Smiley
This example shows a simple smiley face rendered as a static SVG circle, with its center positioned using the `cx` attribute and a fixed radius. The code uses plain SVG markup inside an HTML page, styled with a CSS rule that sets the body’s overflow property. No JavaScript libraries or dynamic data are involved; the visualization is entirely declarative, relying on basic SVG circle elements. The page is built for the React framework but contains no React-specific code in this minimal version.
