This example builds a cartoon face using D3.js and SVG, with layered geometric shapes for eyes, a nose, and a mouth. It demonstrates common SVG features like paths, strokes, and rounded line joins, styled via a separate CSS file. The face is drawn entirely with hardcoded coordinates inside an SVG element, and the code relies on D3’s selection and attribute methods to apply classes and styling. No data or interaction is involved; the focus is purely on static SVG composition and visual design.
