Smiley Face 1
A yellow circle with a black outline and two solid black circles for eyes forms a simple smiley face centered in a 960-by-500 SVG canvas. The SVG uses three `circle` elements with fixed coordinates, fill colors, and a stroke width, all defined directly in the HTML. The rendering is purely static SVG, with no external libraries or data sources. The CSS sets the body margin to zero and hides overflow, ensuring the graphic fills the viewport without scrollbars.
