{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiling face rendered in SVG is built from scratch using D3.js, with a yellow circle for the head, two eyes, a mouth arc, and rectangular eyebrows. The eyebrows animate upward and back down using chained `transition` calls with `duration` settings. The code uses `d3.select` to manipulate SVG elements and `d3.arc` to generate the mouth path, while all positions are computed 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/a88b6ec0463a4ff490a1e2c9652bb5c5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
