{"version":"1.0","type":"rich","title":"Making a face","description":"A smiling face made of SVG shapes animates inside a yellow circle. D3 v7 transitions shrink and regrow the right eye, while both eyebrows shift downward and then return. The mouth is drawn with the `d3.arc` path generator as a partial ring. Elements are grouped and positioned with SVG transform attributes, and chained `transition` calls drive the two-step animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4f1c53c71b9e4432849cf9c5a3d2685a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
