{"version":"1.0","type":"rich","title":"HTML Starter","description":"This example shows a yellow smiley face rendered as an SVG, with animated eyebrows and a mouth that shifts between a filled arc and a thin outline. The face is centered using a translated group element, with circles for eyes and an arc-generated path for the mouth. Built with D3 v6 in a React framework, it uses `select`, `arc`, and chained `transition().duration()` calls to animate the eyebrow position and mouth shape over two seconds. The code demonstrates basic SVG attribute manipulation and data-free geometric drawing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c9f49d7137b14a4d8a38b534e6718197?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
