{"version":"1.0","type":"rich","title":"Face with animated eyebrows and mouth","description":"A face with animated eyebrows and a mouth demonstrates D3.js transitions and SVG rendering. The head and eyes are static shapes, while the eyebrows move vertically using chained `transition` calls in the `animateEyebrows` function. The mouth is a D3 arc path that repeatedly changes its inner radius via `transition.attrTween` and `d3.interpolate`, alternating between open and closed states every 1.5 seconds. The code uses D3 selections and the `arc` generator, with no external data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/458b189d95144a21be7d0103f2e420ae?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
