{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiling face built with D3.js uses basic SVG shapes—circles, rectangles, and an arc path—to demonstrate DOM manipulation and chained transitions. The code selects the SVG canvas, centers a group, and appends a yellow head, eyes, and a mouth using `d3.arc`. Eyebrows animate upward and back via two sequential `transition().duration(2000)` calls, showing non-linear interpolation of transform attributes. The example relies on D3 v5’s `select` and `arc` imports for concise shape generation and timing control.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/160a2b3f037740aa82db8b0e961f07e8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
