{"version":"1.0","type":"rich","title":"Tidied up Bubble Chart - CGPT Add on","description":"This example shows a bubble chart that aggregates total profit by region from a sales records CSV, with each bubble sized by accumulated profit and colored by region. The visualization uses D3 v7’s `d3.csv`, `d3.group`, `d3.pack`, and `d3.hierarchy` to structure and layout the data as packed circles, rendered as SVG. Interactive tooltips display country and profit details via HTML `div` elements, while labels appear inside each bubble. The chart is built in a plain JavaScript environment with a CSS-styled tooltip and hover opacity effects.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/965a04c29ced4077b0fda605f0678915?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
