{"version":"1.0","type":"rich","title":"Let's make a face with D3.js","description":"A smiling yellow face is drawn in an SVG canvas using D3.js, with eyes, eyebrows, and a mouth positioned relative to a centered group. Eyebrows animate upward and back down via chained `transition().duration()` calls, moving the group's transform attribute. The code uses `d3.select`, `d3.arc` for the mouth's shape, and explicit SVG `circle`, `rect`, and `path` elements. The face is styled with a light blue background and black strokes, all rendered dynamically from the viewport height and width.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2dec610125a84dddbfa9d3be9ef1883c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
