A stylized face built from SVG shapes animates its eyes and eyebrows in a looping sequence. The yellow circular head stays static while the eye group shifts vertically, followed by a separate eyebrow group that moves after a delay. The mouth is drawn as an arc path using D3's `arc` generator. The code uses D3 v5 selections and chained `transition.attr` calls on the SVG rectangles and groups to create the coordinated motion.
