This example shows a simple smiley face constructed from three overlapping circles, with a large yellow circle for the head and two smaller black circles for the eyes. The SVG is hard-coded at 960 by 500 pixels, with the face positioned centrally and the eyes offset symmetrically from the center. The rendering uses the SVG `circle` element with explicit `cx`, `cy`, `r`, `fill`, and `stroke` attributes, and the HTML page hides overflow and resets margins via CSS. No JavaScript or external libraries are used; the graphic is purely static SVG markup.
