{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example builds a yellow smiley face with D3.js, animating its eyebrows upward and downward in a looping motion. It demonstrates fundamental DOM selection and manipulation using `d3.select`, `d3.arc` for the mouth, and chained `transition().duration()` calls to move SVG elements. The face is constructed from basic SVG shapes—circles, rectangles, and a path—positioned via `attr` transforms within a centered group. The code uses D3 v5 and renders entirely in SVG without external data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7daa7541757444f1b64fddef43edf552?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
