{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A yellow smiley face rendered in SVG demonstrates fundamental D3.js DOM manipulation. The face uses D3 v5's `select` and `arc` to append a circle, eyes, and a mouth, with the mouth created via the `arc()` generator. Eyebrows, drawn as rectangles, animate upward and downward through chained `transition().duration()` calls, while the mouth also shifts position over two seconds. All elements are positioned within a centered `<g>` group, showing basic SVG construction and data-driven updates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3e6ead70981d42479a6b5f3494d4a7a3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
