{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A yellow smiley face, rendered with SVG shapes, demonstrates fundamental DOM manipulation and animated transitions in D3.js. The example builds the face using appended `circle`, `rect`, and `path` elements, with the mouth generated via the `d3.arc` generator. Both eyebrows, created as rectangles, move up and down through chained `transition()` calls on their containing group, each lasting two seconds and alternating between two vertical offsets. The code uses D3 v5 selection methods and `attr` to position elements, with no external data source, purely illustrating programmatic shape creation and animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/868945b06b8b4bd4a0180a0d4c12243e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
