{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiling face is constructed entirely from SVG shapes, with a yellow circular head, two dark eyes, eyebrows, and an arc-based mouth. The example demonstrates basic SVG composition and D3 selections, then animates the eyebrows by chaining `transition` calls to shift their vertical position. It uses D3 v5’s `select`, `arc`, and `attr` APIs to generate the mouth path and manage transform attributes. A centered `<g>` group positions all features, with fixed pixel constants controlling eye spacing and offsets.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/84c2d30a1a34436a984df22371644f86?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
