{"version":"1.0","type":"rich","title":"01. face with D3.js","description":"A yellow smiley face drawn with SVG circles, rectangles, and an arc path is centered in the viewport. D3.js selections append the facial features, while a chained `transition` with a two-second duration repeatedly moves the eyebrow group up and down. The code uses D3 v5’s `select`, `arc`, and `attr` to construct the face from hardcoded dimensions, demonstrating basic DOM manipulation and animation without external data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/54b0efa3fc084b96a141e76c3a081b86?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
