{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example uses D3.js v5 to build a smiley face from basic SVG shapes. A yellow circle forms the head, with two smaller circles for eyes, rectangular eyebrows, and an arc-based mouth. The eyebrows animate by translating up and down in a loop using chained `transition()` calls with 2-second durations. The code demonstrates fundamental DOM manipulation via D3 selections, `append()`, and `attr()`, while the `arc()` generator from D3’s shape module creates the mouth path. All elements are centered using a translated SVG `<g>` group.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d4d1d6d8158c47f78178dc2217bb36f9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
