{"version":"1.0","type":"rich","title":"Animated happy to evil face (click to see transformation)","description":"A D3.js v6 SVG animation transforms a cheerful, orange face into an evil one. The face features blue eyes that turn red, eyebrows that rotate and translate, and a mouth that changes from a smile to a frown. The user initiates the transformation with a click, triggering sequential `transition()` chains that animate eye color, brow rotation, and the mouth's arc path. The code uses `d3.arc()` for mouth shapes, `d3.interpolateString` for rotations, and `attrTween` implicitly via transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2713e8e97a5a4cc393fab33f0af2f522?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
