{"version":"1.0","type":"rich","title":"Smile Face","description":"A smiling face built with D3.js v6 renders as an SVG with animated eyebrows. The code uses `d3.arc` to draw the mouth and `d3.select` to append circles, rectangles, and a path for facial features. Eyebrows transition vertically in a looping sequence via `transition.attr` and an `on('end')` callback. All geometry is centered by translating a group element, and dimensions are derived from the SVG’s width and height attributes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c9c4b696ff124aefb13604bcace0f892?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
