This example shows a smiley face drawn in SVG, with yellow circular head, black eyes, and an incomplete circular stroke forming the mouth. The code uses raw SVG elements with CSS for styling, including `r`, `cx`, and `cy` attributes set via CSS properties. React 18.2.0 is loaded via a script tag, though no React components are actively used. The SVG is sized at 960 by 500 pixels, and the mouth is created using `stroke-dasharray` and `stroke-dashoffset` to show only a partial arc.
