A yellow smiley face with animated eyebrows is rendered in SVG using D3 v5. The code builds the face from primitive shapes—circles for the eyes, rectangles for the eyebrows, and an arc-generated path for the mouth—demonstrating DOM selection and manipulation via `d3.select` and `d3.append`. The eyebrows repeatedly shift vertically using a chained `transition().duration(2000)` sequence. All positioning relies on fixed numeric coordinates and transforms, with no external data source.
