This example displays a simple smiley face made of three SVG circles: two small black circles for eyes and one larger yellow circle with a black outline for the face. The code uses raw SVG elements within an HTML5 `index.html` file, with attributes like `cx`, `cy`, `r`, `fill`, and `stroke` defining geometry and styling. No data source or JavaScript library is involved; the rendering relies entirely on the browser’s native SVG support.
