This fork of “Let's make a face with D3.js!” builds an SVG smiley face with animated eyebrows using fundamental DOM manipulation. The face includes yellow circular head, two eyes, a nose, and a mouth, all positioned via SVG attributes and transforms within a centered group. The code uses D3 v5’s `select` and `arc` functions to create the facial features, with eyebrows drawn as arc paths that can shift position. A YouTube tutorial in the README supports learning the underlying D3 concepts.
