A yellow circle face with black eyes, eyebrows, and a smile is drawn entirely with D3.js v5 SVG primitives, including `circle`, `rect`, and an `arc()` path for the mouth. The face is centered within an SVG using a translated `g` group, and the eyebrows animate upward and back down via chained `transition().duration()` calls. The geometry uses constants for spacing and offsets, and the code demonstrates selection, attribute setting, and the `arc` generator from the `d3` module.
