{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A D3.js smiley face uses SVG primitives—circles, rectangles, and an arc path—to draw a yellow head, eyes, moving eyebrows, and a mouth. The animation repeatedly translates the eyebrow group up and down via chained `transition().duration()` calls, demonstrating DOM manipulation. The code constructs the face from scratch using D3’s `select`, `append`, and `attr` methods, and computes the mouth’s shape with the `arc` helper, all rendered in an SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c3412ac506e74c1a8e67b74108c89f21?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
