A yellow circle with a black outline and two smaller black circles for eyes forms a simple smiley face. The SVG is rendered directly in an HTML page using the `circle` element, with the face centered at 960 by 500 pixels. The rendering relies on basic SVG shape attributes for positioning, fill, stroke, and stroke width, with no external data source or processing library involved. The page uses a minimal stylesheet to remove margins and hide overflow, and the code is self-contained within a single `index.html` file.
