A yellow smiley face is drawn on an SVG canvas using D3.js, with two eyes, eyebrows, and a mouth created via basic shapes and an arc path. The entire face is centered with a group translation, and the eyebrows animate upward and back down over four seconds using chained `transition` calls. The code imports `select` and `arc` from D3 v5, sets circle, rectangle, and path attributes programmatically, and relies on SVG for rendering.
