Three stylized people, each composed of simple SVG shapes—a head, body, eyes, smiling mouth, arms, and legs—stand in a row and animate in a coordinated dance. The D3.js v6 code binds an array of three data objects to group elements and uses `selection.append` to draw each body part. Legs swing back and forth while arms wave repeatedly through chained `transition` calls with rotation transforms, creating a looping, cheerful motion.
