This example draws a simple, animated face using D3.js v5. A yellow circle serves as the head, with eyes, eyebrows, and a mouth composed of SVG shapes. The code uses `d3.select` and `d3.arc` to construct the facial features, and it animates the eyebrows by chaining `transition().duration()` calls to move the eyebrow group vertically. The face is centered using SVG attribute retrieval and a `transform` translation.
