{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiling face built from D3.js SVG shapes animates its eyebrows upward and back down. The code uses `d3.select` to append circles, rects, and an `arc()`-generated path onto a 960×500 SVG, with a yellow circular head, black-outlined eyes, and a curved mouth. Eyebrow motion is driven by chained `transition().duration(2000)` calls that translate the eyebrow group, demonstrating sequential SVG attribute tweening.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/eb6ffb8b7bdf4371a2a592ae65aa7bf7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
