This example displays a simple cartoon smiley face drawn with scalable vector graphics. The face consists of a large yellow circle, two eyes, and a red circular mouth, all rendered using inline SVG elements within an HTML page. The page uses pure HTML and CSS, with no JavaScript, to style the SVG shapes. CSS rules define the background color and override the fill colors of the eyes and mouth to green, while the SVG attributes set the initial positions, radii, colors, and stroke widths for each circle.
