{"version":"1.0","type":"rich","title":"Smiley","description":"A smiling face is rendered as a static SVG figure, with a purple circular head, two eyes, and a curved mouth drawn using a D3 arc path. The eyebrows, created as rectangles, animate up and down in a repeating sequence via chained `transition.attr` calls. The visualization uses D3 v5's `select`, `arc`, and SVG element creation, with all coordinates computed relative to the viewport’s center.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4249121c2a76413babf90e183b0ea66b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
