This example displays a simple yellow smiley face drawn with SVG primitives, centered on a 960×500 canvas with a black stroke and two circular eyes. It uses plain HTML and inline SVG elements—`<circle>` tags with explicit `cx`, `cy`, `r`, `fill`, and `stroke` attributes—rather than a JavaScript library like D3. The page sets `margin: 0` and `overflow: hidden` on the body to remove default spacing. The rendering is static SVG, with no interactivity, animation, or data binding shown in the code.
