This example shows a stylized face rendered with red circular head, eyes, animated eyebrows, and a curved mouth. The eyebrows move up and down through a two-stage transition sequence. The visualization uses D3 v7 to draw SVG shapes, including circles for the head and eyes, rectangles for eyebrows, and arc-generated paths for the right eyebrow and mouth. The code applies D3 transitions to animate the eyebrow group’s vertical position over two seconds.
