{"version":"1.0","type":"rich","title":"D3: A simple packed Bubble Chart","description":"A packed bubble chart displays a static set of food items and their associated counts as proportionally sized, colored circles arranged in a tight cluster. The visualization uses D3 v4’s `d3.pack` layout on a hierarchical dataset, with each leaf node rendered as an SVG circle and labeled with its name and count. Color is assigned via `d3.scaleOrdinal` with `d3.schemeCategory20`, and text size scales relative to each circle’s radius.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-3d6be4be0ef9f6977ec6718b2916d168?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
