This example shows a simple smiley face drawn with two dark eye circles and a large yellow circle bounded by a thick black stroke. The illustration uses no data or interactive behavior—only static SVG elements. The entire graphic is constructed directly in the `index.html` file using inline SVG markup, while a CSS rule hides page margins and scrollbars. The code relies on the SVG `<circle>` elements within an HTML page, styled with fill and stroke properties, without any JavaScript libraries or data sources.
