This example shows a simple smiley face drawn as three circles on a yellow circular background with a black outline. The SVG markup places two smaller circles for eyes and a larger circle for the face, all rendered statically without animation or interaction. The code uses raw SVG elements within an HTML page, setting attributes like `cx`, `cy`, and `r` directly. The rendering approach is SVG with a fixed viewport of 960 by 500 pixels, and no external JavaScript libraries are required.
