{"version":"1.0","type":"rich","title":"Untitled","description":"This example animates the morphing of one SVG path into another using D3’s `transition.attrTween` and a custom path interpolation function. The path alternates between two cubic Bézier shapes in an infinite loop, with each transition lasting two seconds and using uniform distance sampling for smooth point-by-point interpolation. The code references `d3.select`, `d3.active`, and `getTotalLength`, while importing D3 v6 from a CDN. The included `province.csv` file contains COVID-19 statistics for Chinese provinces, though it is not loaded or visualized in the rendered output.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
