{"version":"1.0","type":"rich","title":"Happy Halloween!","description":"A jack-o'-lantern face appears on a dark background, constructed from SVG shapes including ellipses, polygons, and a path-drawn stem. Geometric features—eyes, nose, and a curved mouth—initially glow yellow, then repeatedly transition to black and back, simulating a flickering candle. The piece uses D3.js v5 for SVG rendering and chained `transition().duration(1000)` calls to animate the color shifts. The pumpkin body, teeth, and stem are statically colored with fills, while the `arc()` function generates the mouth's curved path.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7a282119288e4659b85b1ac2e102b069?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
