{"version":"1.0","type":"rich","title":"Let's make a face with D3.js","description":"A smiling face rendered in SVG is drawn with D3.js, using geometric shapes for the head, eyes, eyebrows, and a mouth created with the `d3.arc` path generator. The example demonstrates a looping animation where the eyebrows repeatedly move downward and back upward via chained `transition.attrTween` calls, while the static face elements remain fixed. The code relies on D3 selections and attribute manipulation, with the SVG canvas set to 960 by 500 pixels and centered via a transformed group.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ad4858f2cbd74ae1bf1cf213ccef283c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
