{"version":"1.0","type":"rich","title":"Let's make a face with D3.js","description":"A yellow smiley face is drawn with D3.js using SVG shapes: a circle for the head, two circles for eyes, rectangles for eyebrows, and an arc-generated path for the mouth. The brows animate upward via chained `transition().duration()` calls on a group, though the second transition repeats the same transform. The code uses the `select`, `arc`, and named attributes from the D3 v5 API, with dimensions set from the SVG's height and a centered `g` transform.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/edd2ea3dd0c94c69b11c1fef1893c40d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
