A yellow face with blue eyes, eyebrows, and a curved mouth is drawn in an SVG canvas using D3 v7. The visualization constructs the face from primitive shapes—circles for the eyes, an arc-generated path for the mouth, and rectangles for the eyebrows. The eyebrows animate vertically over four seconds using D3's `transition` and `duration` methods, shifting them up and then back down. The code explicitly sets dimensions and positions based on the SVG's width and height attributes.
