A yellow smiley face with animated eyebrows is drawn in SVG, demonstrating fundamental D3.js DOM manipulation. The code selects the SVG, appends groups, and builds the face from circles, rectangles, and an arc-generated mouth path. Using D3's `transition()` method, the eyebrow group moves vertically over four seconds, creating a blinking-like effect. The example relies on D3 v5, importing `select` and `arc` from the main bundle, with coordinates based on the SVG's dimensions.
