{"version":"1.0","type":"rich","title":"Untitled","description":"A yellow circle with a black outline, positioned at the center of an SVG canvas, gradually transitions its fill to red and back to yellow over a five-second animation. The circle is styled as a face with two eyes, rectangular eyebrows, and a mouth drawn using D3's `arc` path generator with a semicircular inner and outer radius. The code uses `d3.select` and `transition.style` to animate the fill, while all facial features are appended as SVG elements within a centered group.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
