A cartoon face rendered in SVG uses D3 v5 to build a yellow circle head with black eyes and an arc-based mouth. Eyebrows, drawn as rectangles, animate vertically through chained `transition` calls on a group element. The code leverages D3’s `select` and `arc` APIs, with static attributes for positioning and a repeated eyebrow movement lasting two seconds per phase, demonstrating basic SVG construction and timed animation.
