Fork of Create a face with d3.js!
This example shows a yellow smiley face drawn in SVG using D3.js, with its eyebrows animating up and down in a repeating cycle. The face is assembled from circles, rectangles, and a path created with D3’s `arc()` helper, all positioned within a centered `<g>` group. The code uses D3 v7, loaded via UNPKG, and demonstrates `import` of `select` and `arc` from the D3 module. Eyebrow motion is achieved with chained `transition().duration()` calls that alternate the group’s transform attribute.
