This example shows a simple smiley face drawn as a set of three SVG circles on a yellow background. The face is rendered using raw SVG elements within an HTML page, with a large yellow circle for the head and two smaller black circles for the eyes. The visualization relies on basic CSS for page styling, including margin reset and centered text, while the SVG markup defines the shapes with explicit coordinates and stroke properties. The code demonstrates a minimal static graphic without any JavaScript libraries or interactive behavior.
