{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A D3.js example builds a yellow smiley face with eyes, eyebrows, and an arc-based mouth, then animates the eyebrows upward and back down using chained `transition` calls on SVG `rect` elements. The face is centered via a `g` transform, with `d3.arc` generating the mouth path. The code selects an SVG, appends shapes with explicit pixel offsets, and relies on D3 v5’s `select`, `attr`, and `transition` APIs to demonstrate fundamental DOM manipulation and animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3b73d0c430674c3492cc68ed8797945d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
