This example builds a cartoon face out of basic SVG shapes—circles for the head and eyes, rectangles for eyebrows, and an arc-generated path for the mouth—all centered within an SVG canvas using D3.js v5. The code imports `select` and `arc` from the D3 library to append elements and compute the mouth’s path. A chained `transition().duration(2000)` sequence animates the eyebrows up and down, creating a winking expression. The layout uses fixed numeric constants for spacing and offsets, with no external data source.
