Kishon Fork of Create a face with d3.js!
This example draws a smiling face using D3.js, rendered as scalable vector graphics (SVG) with a 2000-millisecond animated eyebrow movement. The visualization imports `select` and `arc` from the D3 library, building the face from basic shapes: a yellow circle for the head, two circles for eyes, rectangles for eyebrows, and an arc path for the mouth. The code demonstrates API usage by chaining a two-phase `.transition()` on the eyebrow group, shifting its vertical position to create a subtle, repeated gesture.
