A yellow smiley face with animated eyebrows demonstrates fundamental DOM manipulation with D3.js v5. The code selects an SVG element, appends circles for the face and eyes, rectangles for eyebrows, and an arc path for the mouth using d3.arc(). D3 transitions move the eyebrow group up and down over four-second intervals. Static SVG attributes set positions and colors, while the transition chain animates the transform attribute.
