{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A D3.js code example builds a yellow smiley face from SVG primitives, including a circular head, eyes, eyebrows, and a mouth created with the `d3.arc` path generator. The face is centered via a translated group, and the eyebrows are rectangles that move up and down using chained `transition()` calls with a two-second duration each. The demo relies on D3 v5's selection methods (`select`, `append`, `attr`) to construct the shape and animate its parts directly in the browser.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/96c87d10059343af8e2a20f9c2786280?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
