A yellow circle face with black eyes, animated eyebrows, and a curved mouth is drawn using SVG. The code builds the face by layering a circle, eye groups, and rectangles for eyebrows, then animates the eyebrows upward and back down using chained D3 transitions. The mouth is created with a d3.arc path. The example uses React-compatible starter code and renders entirely with D3 v5's select and arc modules.
