A pink SVG face with blinking eyebrows and animated facial features responds to simple D3 transitions. The code builds the face by nesting grouped shapes—circles for the head, eyes, and nose, plus rectangles for the eyebrows and an arc-generated path for the mouth—within a central `<g>` element using D3 v6 selection and `arc` API methods. Eyebrows slide and stretch through chained `.transition()` calls, creating a playful, looping expression. All shapes are positioned relative to the group, keeping the face centered as it animates.
