Let's make a face with D3.js!
This example uses Vue.js and D3.js v5 to draw a smiling face composed of basic SVG shapes. The face consists of a dark orange circle for the head, black circles for the eyes, and a mouth created with the `d3.arc` path generator. SVG groups with `translate` transformations position the eyes relative to the face center, while the arc’s `innerRadius` and `outerRadius` define the smile’s thickness. The code demonstrates integrating D3 selections with Vue’s reactive data model to manage dimensions and shape attributes.
