This example draws a simple cartoon face using D3.js version 5 and SVG. It renders a yellow circle for the head, two black ellipses for eyes, and an empty path for the mouth. The code uses D3’s `select` and `attr` methods to position each shape based on the SVG’s fixed width of 960 and height of 500. All elements are placed with relative coordinates, such as `width/2.5` for the left eye, demonstrating basic geometric composition through SVG primitives.
