{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A D3.js animation builds a smiling face from SVG primitives: a yellow circle for the head, two circles for eyes, rectangles for eyebrows, and a path for the mouth. The eyebrows animate by translating vertically in a repeated two-second loop, using chained `transition` calls to move them up and down. The code constructs the face with `select`, `append`, and `attr`, and calculates the mouth’s arc with the `arc` function, all within an SVG canvas sized 960 by 500 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b645375c3be040c0951d2a31c2a2565f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
