{"version":"1.0","type":"rich","title":"Let's make a face with D3.js","description":"A smiling face is drawn as a yellow circle with two eyes, animated eyebrows, and an arc-shaped mouth, all rendered in SVG. The animation uses D3 transitions to move the eyebrows up and down over two seconds. The code leverages `d3.select`, `d3.arc`, and SVG `circle`, `rect`, and `path` elements within a fixed 960×500 viewport, with the face centered via a group transform.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ab2e82d12f63481c940dc445601f97f5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
