This example builds a stylized yellow face from basic SVG shapes using D3 v5. The face features animated eyebrows, eyes, and an arc-based mouth, all centered within an SVG canvas. The eyebrows transition vertically via `transition().duration(2000)` to create a subtle bobbing motion, while the mouth is drawn using the `arc()` generator. The code uses `select()` to manage SVG elements and demonstrates ES6 module imports for structured D3 code.
