{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A yellow smiley face with animated eyebrows demonstrates fundamental DOM manipulation with D3.js. The face is built entirely with SVG shapes selected and appended via `d3.select` and `selection.append`, including circles for the head and eyes, rectangles for eyebrows, and a path generated with `d3.arc` for the mouth. Eyebrows animate upward and back down using chained `transition.duration` calls that modify their `transform` attribute. The example uses D3 v5 and relies on SVG attributes like `cx`, `r`, and `d` to construct the static face.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e280d36a8af4424ea3f51f4957de8095?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
