This example constructs a simple cartoon face using D3.js v5, rendered as SVG elements. The code uses the `select` function to target the SVG canvas, then appends and positions a yellow circle for the head, two black circles for the eyes, and a path for the mouth. The mouth’s arc shape is generated using the `arc` function, specifying inner and outer radii and angular ranges. All elements are centered through a group translation, using static, hard-coded values for spacing and dimensions.
