A smiling face built from D3.js SVG shapes demonstrates sequential animation with transition chains. The yellow circle, eyes, and arc-based mouth are drawn using D3 selections and the `d3.arc` helper, while two rectangular eyebrows animate upward and back down over four seconds. The movement uses chained `transition().duration()` calls on the eyebrow group's transform attribute, illustrating basic DOM manipulation and timed updates.
