A face drawn with D3.js v6 animates its eyebrows up and down. The SVG face shows a yellow circular head, two eyes, rectangular eyebrows, and a curved mouth created with the `d3.arc` generator. The view is centered using an SVG group translation based on the width and height attributes. Eyebrow movement uses chained `transition` calls to shift the group's transform over 2000 milliseconds each way.
