{"version":"1.0","type":"rich","title":"First D3 demo","description":"A yellow smiley face rendered as SVG circles, a red nose, and a mouth drawn with the `d3.arc` path generator. D3 selections append shapes to a centered group, with the right eyebrow animating upward and downward via two sequential `transition.attr` calls on a rectangle. The code imports `create`, `select`, and `arc` from D3 v6 and uses static dimensions without external data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fa8674dc89c44be4b107003fb4170933?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
