A yellow smiley face with animated eyebrows is drawn in SVG using D3.js v5. The face is centered via a translated group, with circles for eyes, rectangles for eyebrows, and an arc-generated path for the mouth. The eyebrows transition upward and back downward over two seconds each using chained `transition` and `duration` calls, demonstrating fundamental DOM manipulation and animation with D3's `select`, `arc`, and transition API.
