This example builds a cartoon face using D3.js v5 and SVG. The code draws a red circle for the head, two white circles for the eyes with black strokes, and a curved mouth created with the `d3.arc()` generator. All shapes are positioned relative to the SVG’s width and height, with eye offsets and the mouth placed inside a transformed group. The visualization relies entirely on basic SVG shape primitives and D3’s arc path helper, with no external data.
