{"version":"1.0","type":"rich","title":"11506566 - Smiley face","description":"A cartoon smiley face with animated eyebrows and a mustache, beard, ears, teeth, and hair is rendered in SVG. The face is constructed using D3 selections and shape generators, including `arc` for the mouth and `line` with `d3.curveBasisClosed` for the mustache and beard. Eyebrows animate via chained `transition().duration(2000)` calls that move them up and down. The example demonstrates fundamental DOM manipulation with D3 v5, building all elements from hardcoded coordinates and attributes rather than external data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bf2147a6680747f3a3ad6da5e0ff1727?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
