{"version":"1.0","type":"rich","title":"D3 tutorial","description":"A minimal D3 tutorial example renders a cartoon face in SVG, with a yellow circle head, eyes, and a smile drawn via the `d3.arc` path generator. The code uses D3 v6 selections to append elements, and demonstrates `transition` with chained `.duration()` calls to animate the eyebrows up and down repeatedly. The React-free setup loads D3 from a CDN in an HTML page, with the styling applied through external CSS that hides page margins and overflow.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c44f162a326e4188bca4a998b2ce9acf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
