Let's make a face with D3.js!
This example demonstrates how to build a cartoon face using D3.js v5 and SVG primitives. The code creates a yellow circular head, two eyes, rectangular eyebrows, and a curved mouth path using the `arc` generator. All elements are centered via a translation transform on a nested `<g>` group. The visualization uses static coordinates and dimensions rather than data binding, highlighting D3’s utility for direct SVG manipulation.
