A yellow circular face with black features, including eyes, eyebrows, and a frown, is rendered in SVG. The eyebrows animate upward and then return to their original position using a chained `transition.attr` in D3 v7. The code builds the face using `select`, `arc`, and `append`, with a `g` element centered via a transform. Static constants define the eye spacing, offsets, and mouth arc, all drawn within a 960 by 500 SVG canvas.
