{"version":"1.0","type":"rich","title":"Fork of Fork of Let's make a face with D3.js!","description":"A D3.js smiley face animates by moving its eyebrows up and down in a looping transition. The face is built entirely with SVG primitives—circles for the eyes, rectangles for the eyebrows, and an arc-generated path for the mouth—positioned within a centered group. Using `d3.select`, `d3.arc`, and chained `transition().duration()` calls, the code shifts the eyebrow group’s vertical translation between two offsets. A black background and yellow face with black strokes create clear visual contrast. The example demonstrates fundamental DOM manipulation and SVG rendering with D3 v5.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b929fbe4c9a34a14b4566c9e55137747?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
