{"version":"1.0","type":"rich","title":"Let's make a face","description":"A smiley face, drawn with SVG circles and an arc path, animates its eyebrows in a looping sequence in a D3.js visualization. The code builds the face by manipulating SVG groups and shapes, using D3's `select` and `append`. A `transition` with a 2000-millisecond duration shifts the eyebrow group up and down, creating the expression change. The face's construction relies on explicit pixel coordinates and D3's `arc` generator for the mouth, with a yellow circle serving as the head.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ba7158d7790c491484ead1634fc866de?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
