A simple cartoon face built from SVG primitives appears on a yellow circular head with black outlines, featuring two eyes, movable eyebrows, and a mouth drawn as an arc path. D3 selections and transitions animate the eyebrow group’s vertical position over two seconds, first lowering and then raising it. The code imports `select` and `arc` from D3 v5, uses SVG circles, rectangles, and paths, and runs within a React-created bundle on a bare HTML page.
