A yellow cartoon face with eyes and a moving mouth is rendered in SVG. D3.js v5 selections construct the head, eyes, and eyebrows, while the mouth uses the `d3.arc` path generator. The eyebrows are animated using chained `transition` calls with a 2000-millisecond duration, shifting them upward and back down. The code imports `select` and `arc` directly from the D3 module.
