This example uses D3 v5 to draw a stylized yellow face, including a circular head, two eyes, and eyebrows, within an SVG. The eyebrows are animated using a chained `transition` to move down and back up. The mouth is created using D3's `arc` generator, and all elements are positioned relative to the SVG's center using a `g` element and transformations. The code applies shapes like `circle` and `rect`.
