This example draws a simple smiley face using raw SVG elements within a single HTML file. It uses the `circle` element to create the face and eyes, with CSS setting the page margin to zero and hiding overflow. The face is rendered as a yellow circle with a black stroke, and two smaller black circles serve as the eyes; the code includes a typo in the `stroke` attribute of the eye circles. The visualization demonstrates basic SVG shape creation without any JavaScript or external libraries.
