A yellow face with black-outlined eyes and a curved mouth is drawn using D3.js v7, with SVG circles, rectangles, and a path forming the features. The code uses D3's `select` and `append` to build the scene, and `transition().duration()` to animate the eyebrows shifting down and up over two seconds. Elements are positioned relative to the SVG's center using a transformed group, and the mouth is rendered with D3's `arc` function.
