A yellow circle with black facial features is drawn as a smiling face using D3.js v5. The code builds the face from SVG elements—a circle for the head, two circles for eyes, and an arc path for the mouth—positioned within a centered group. The eyebrows are animated with chained `transition().duration()` calls, shifting them downward and upward repeatedly. It uses `select` and `arc` from the d3 module on a static SVG canvas.
