HTML Smiley
This example shows a simple smiley face drawn as three SVG circles: a large yellow head and two smaller black eyes, all positioned within a 960-by-500 pixel viewport. The code uses plain SVG elements inside an HTML file, with inline CSS to reset the page margin and hide overflow. No JavaScript or data sources are involved; the rendering relies solely on static SVG circle attributes for coordinates, radii, fill, and stroke styling.
