{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiling face built with D3.js demonstrates fundamental DOM manipulation through SVG shapes. The code appends a yellow circle for the head, two dark circles for eyes, and a semi-circular mouth created with the `arc` generator. Eyebrows are rectangles that animate vertically using chained `transition` calls with a 2000-millisecond duration, moving up and down repeatedly. The example relies on D3 v5’s selection methods like `append` and `attr`, with all elements centered via a translated group.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5d3524fbf9a14f1fadb9a8ca8ab00a21?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
