A yellow smiley face is drawn using D3.js v5's `select` and `arc` APIs, with SVG circles for the eyes and a path for the mouth. The eyebrows, rendered as rectangles, animate upward and back downward over four seconds via chained `transition().duration(2000)` calls. The code demonstrates fundamental DOM manipulation by building the face from scratch in an SVG container, using hardcoded dimensions and positions.
