A stylized, yellow SVG face with black-outlined features and animated eyebrows. The face is constructed using D3 primitives: circles for the face and eyes, and rectangles for the brows. The entire face is centered within the SVG, with the mouth drawn as an arc path. The eyebrows animate via chained `transition` calls, moving downward over one second and then returning to their original position over two seconds. The code imports `select` and `arc` from D3 v5.
