This example renders a simple cartoon face using SVG primitives within a D3 v7 selection. The code builds the face from basic shapes, including circles for the head and eyes, rectangles for the eyebrows, and a path generated with the `d3.arc` helper for the mouth. All elements are positioned relative to a central group translated to the middle of the 960x500 SVG canvas. The styling is applied through the `styles.css` file, which hides the page margin and defines stroke properties for the drawn lines.
