{"version":"1.0","type":"rich","title":"Let's make a face with d3.js!","description":"A yellow face built with SVG circles, rectangles, and arcs animates its expressions. The face’s eyebrows shift downward and upward via chained `transition().duration()` calls, while a smile arc flips into a frown using the same timed transforms. The code constructs the face by appending SVG groups and shapes with d3 v5’s `select` and `arc` APIs, positioning elements relative to the center of a 960×500 SVG. Static facial features—eyes, irises, and a mouth—are drawn with basic geometry, while the background turns red through a direct DOM style update.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/63f8e1c54b6745feb6a046175ce90aeb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
