Let's make a face with D3.js!
A yellow circle face is drawn with D3.js, featuring two eyes, animated eyebrows, and a smile-shaped mouth rendered as an arc. The SVG is centered and built using D3 selections, with the mouth created via the `arc` generator. Eyebrows transition vertically using `transition().duration(2000)`, shifting their position over two seconds before settling. The example uses D3 v5 within a React framework, rendering all elements as SVG with animation.
