A yellow smiley face is rendered in SVG, with the head as a circle, two eyes, and a mouth drawn using d3.arc. Animated eyebrows repeatedly move up and down via d3 transitions, changing their transform attribute over two seconds. The face is centered using D3 selections and attribute manipulation, with all shapes positioned relative to the SVG’s center. The visualization uses d3.select, d3.arc, and transition calls, with no external data source.
