{"version":"1.0","type":"rich","title":"Untitled","description":"A D3.js animation draws a yellow smiley face whose eyebrows bob up and down. The code builds the face from SVG shapes—circles for the eyes and head, rectangles for the brows, and an arc-generated path for the mouth—centered via a translated group. Using `d3.select` and `d3.arc`, it applies chained `transition().duration()` calls to animate the eyebrow group’s vertical position, creating a looping motion. The rendering is a lightweight DOM manipulation example with no external data, running entirely in the browser.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b94237e12e6f497eb835e9b9081f5f59?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
