A yellow face with black outlines is drawn using D3 selections and SVG shapes, including circles for the head and eyes and rectangles for eyebrows. The eyebrows animate up and down via chained `transition().duration()` calls, while a mouth is created using the `d3.arc()` generator. The code uses `d3.select` and `d3.arc` from D3 v6, with explicit SVG attributes for positioning and sizing.
