{"version":"1.0","type":"rich","title":"circle popup","description":"Six colored circles of varying sizes pop into view on a light green background, each growing from a radius of zero to its assigned size over an eight-second staggered transition. The circles remain static once fully expanded, with no further movement or interaction. The visualization uses D3.js selection joins with enter, update, and exit handlers, applying the `transition` API with `easeLinear` for the fast update phase. Hardcoded data defines each circle's position, radius, and fill color, with opacity set to 0.708 for a translucent effect.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2f10a40e571f48b4a767bf21056119e7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
