A yellow circle face with black outlines displays two eyes, eyebrows, and an arc-shaped mouth on an SVG canvas. The eyebrows animate vertically, moving down and back up over a sequence of transitions. Built with D3 v5, the visualization uses `select` and `arc` from the D3 module to construct the facial features, with `transition` and `duration` controlling the eyebrow movement. The code generates the mouth using an arc generator with specified inner and outer radii and angles.
