A large yellow circle with a black outline forms the base of a smiley face, centered on a 960 by 500 SVG canvas. Two smaller black circles serve as eyes, positioned symmetrically around the horizontal center. The page uses plain HTML and inline SVG elements—specifically the `circle` tag—to draw the shapes, with the CSS rule `overflow: hidden` on the body preventing scrollbars. No JavaScript libraries are involved; the rendering is entirely static SVG.
