A yellow smiley face is drawn with circles, rectangles, and an arc path, using D3.js v5 selections and the `d3.arc` helper to generate the mouth. The SVG is centered on a 960×500 canvas, and the eyebrows animate upward and back down via chained `transition` calls with specified durations. Eye spacing, radius, and eyebrow offsets are defined as constants, while the face itself is composed from static shape elements without a data join.
