{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A yellow smiley face, rendered as SVG primitives, appears centered on a dark background. D3.js code appends a circle, eyes, eyebrows, and a mouth path created with the `arc` function. The animation uses chained `transition().duration()` calls to move the eyebrows down and back up over two seconds, demonstrating fundamental DOM manipulation. The example uses d3.v5 with the `select` and `append` APIs to build the figure.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a81e3dc6e6c64ad18fd4a820dd0d0d55?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
