This example renders a stylized smiley face as an SVG graphic using D3.js. The face is composed of a yellow circle with eyes, spectacles, a mouth, and a red tongue. The code uses d3-selection to append SVG elements and d3-shape’s `arc()` generator to create the round spectacle frames, the mouth arc, and the tongue shape. Rectangles, rotated via SVG transforms, form the right eye and the bridge of the glasses.
