A yellow circle face with eyes, brows, and a mouth is drawn using D3.js v5 SVG primitives. The face is centered via a transformed group, and the eyebrows animate upward and back down using chained `transition().duration()`. The mouth is created with the `d3.arc` shape generator, while circles and rectangles define the eyes and brows. The code imports `select` and `arc` from D3 and uses SVG attributes for positioning.
