This example builds a simple smiley face using SVG primitives. It shows a large yellow circle as the head, with two smaller black circles positioned inside it to represent eyes. The visualization is created entirely with static SVG elements, including explicit `cx`, `cy`, `r`, `fill`, and `stroke` attributes. The rendering relies on the browser’s native SVG support, with no external JavaScript libraries or data sources involved. The layout is fixed within a 960×500 viewport, and the face is centered accordingly.
