A yellow face with black-outlined eyes, eyebrows, and a smiling mouth is drawn using D3.js. The SVG portrait is centered, with circles for the eyes and an arc-generated path for the mouth. Animated transitions move the eyebrow rectangles upward and back downward over two seconds each, creating a subtle expressive motion. The example uses D3 v7 selections, the `arc` helper, and chained `transition().duration()` calls.
