Fork of Create a face with d3.js!
A simple, animated face is drawn with yellow circular head, black-outlined features, and eyebrows that bounce over a two-second cycle. The example demonstrates basic D3.js v7 shape construction with SVG, using `circle`, `path`, and `g` elements, and applies a transition to the eyebrow group’s transform attribute. It imports `select` and `arc` from the `'d3'` module to select the SVG and compute the mouth path, with an arc helper defining the smile’s inner and outer radii and angles. The animation runs continuously without external data, relying entirely on generated geometry.
