{"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 in D3.js. The face is drawn using SVG shapes, including a circle for the head, eyes, rectangular eyebrows, and a mouth path created with the `d3.arc` helper. The eyebrows move upward and downward through chained `transition().duration(2000)` calls, altering their vertical translation. The example uses D3 v5 selections to append and style SVG elements within a centered group, illustrating basic data-driven document updates without external datasets.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/93a5bd16d7934799a1f5e4e8e2a54b62?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
