{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A D3.js example draws a yellow smiley face with SVG shapes, then animates its eyebrows in a bouncing motion. The face is centered using an SVG group with a translation transform, and its features are built from circles, rectangles, and an arc path generated with the `d3.arc` function. Eyebrows transition vertically via chained `transition.attrTween`-like `transition().duration()` calls, moving down and back up repeatedly. The code uses D3 v6 selections and transitions, with no external data source, relying purely on geometric constants for layout.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dba926d9eca5419d886fa28ee1515bba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
