{"version":"1.0","type":"rich","title":"D3 Face twisty eyebrows","description":"A yellow circle face with black stroke holds two black eyes and a smile-shaped mouth. Its thick black eyebrows rotate inward and outward in a looping animation, tilting up and down around their centers. The piece uses D3.js v7 with SVG elements, applying chained `transition()` calls to animate the `transform` attribute of each eyebrow line over two-second intervals. The mouth is drawn as an arc path using D3's `arc()` generator.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6cea2a94ada144fabe87450f83a02877?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
