A fork of an earlier D3.js face-building exercise, this piece renders a static SVG cartoon face and then animates its eyebrows in a looping up-and-down motion. The face is constructed from basic geometric primitives like circles, rectangles, and an arc-based mouth, with features centered and positioned using transforms. The animation relies on chained `transition().duration()` calls to move the eyebrow group, while the overall drawing is handled with D3 selections and the `arc` generator from the d3-shape module. All elements are rendered in an SVG container.
