A smiling face drawn with SVG shapes animates its eyebrows in a playful blinking motion. The yellow circle face, black eyes, and curved mouth are constructed using D3's `arc` and basic SVG circle elements. Eyebrow movement is achieved through chained `transition().duration(200)` calls that shift the path's transform attribute up and down. The visualization uses D3 v6 and renders entirely in SVG with no external data source.
