This example shows a simple yellow smiley face built with three black circles on a 960 by 500 SVG canvas. The large yellow circle forms the face, while two smaller black circles serve as the eyes, all rendered directly with inline SVG elements. The code uses the HTML5 `<svg>` element and its `<circle>` API, styling shapes via the `fill` and `stroke` attributes, with a black `stroke-width` of 5 for the face outline. No external data or JavaScript libraries are used, relying purely on static markup.
