The eyebrows are rectangles that animate upward and back down using chained `transition.attr` calls over two seconds each, demonstrating fundamental DOM manipulation. All shapes are appended to a central group translated to the SVG’s center, with coordinates computed from the viewport’s width and height.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
