This example presents a simple, animated face constructed entirely from SVG primitives. A yellow circle with a black outline forms the head, while two circles serve as eyes and two rectangles act as eyebrows. The eyebrows undergo a looping transition that raises and lowers them over a two-second duration. The visualization is built using D3 version 7, importing functions like `select` and `arc`, and relies on `transition` for animation. The mouth is a path generated from an arc with specified inner and outer radii and angles.
