Fork of Create a face with d3.js
This example shows a smiley face drawn with D3.js v7 SVG primitives, including a yellow circular head, two eyes, rectangular eyebrows, and an arc-shaped mouth. The face is centered using a group transformation, and the eyebrows animate upward and back down over four seconds using chained `transition` calls with `attr` tweening. The code imports `select` and `arc` from D3 and loads the library via UNPKG, demonstrating local ES6 module imports and dynamic SVG attribute updates in a VizHub environment.
