This example renders a cheerful yellow face with eyes, eyebrows, and a mouth as animated SVG shapes. The face is centered and drawn using D3 v5 primitives like `circle`, `rect`, and `arc`, with the eyebrows moving through a sequence of D3 transitions. The code imports `select` and `arc` from D3 and manipulates SVG attributes directly, showcasing a simple, playful animation built with React and D3’s SVG rendering.
