{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A D3.js animation builds a smiley face from SVG primitives: red circle head, two eyes, a mouth formed by an arc path, and rectangular eyebrows. The eyebrows are the focus, moving up and down through chained `transition().duration()` calls on a group's `transform` attribute. The code demonstrates fundamental DOM manipulation using methods like `select`, `append`, and `attr`, and computes the face's layout from the SVG's width and height attributes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bb5f237055c640eb97b446a1eb09757c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
