A yellow face with black-outlined features animates its eyebrows in a repeating bounce, rising and falling over two-second intervals. The face is built with D3 selections and SVG shapes: a circle for the head, two circles for eyes, rectangles for eyebrows, and a path generated with the D3 `arc` generator for the mouth. The entire composition is centered within an SVG canvas using a translated group, and the eyebrow motion is controlled by chained D3 transitions that alternate the group's vertical position.
