A face built from basic SVG shapes appears in the center of the canvas, with a yellow circle for the head, two dark eyes, and a semicircular mouth. The example demonstrates how to compose a figure using D3 v5’s `select` and `arc` APIs, positioning elements through translation and coordinates. The code calculates dimensions from the SVG attributes and places the face’s components relative to the viewport center, showing a simple approach to building custom visualizations with D3’s drawing utilities.
