{"version":"1.0","type":"rich","title":"D3","description":"A yellow circle with eyes, eyebrows, and a mouth forms a smiling face, rendered as SVG elements. The right eyebrow animates upward and back down over four seconds using D3 transitions. The face is centered in a 960×500 viewport, with the mouth drawn via the `arc` generator and all shapes grouped and translated using D3's `select` and `append` methods. The animation runs in an infinite loop, triggered by chained `transition().duration()` calls on the eyebrow rectangle.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2c82746c872d40ab91c2a96b5828a107?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
