{"version":"1.0","type":"rich","title":"Circle Bubble of BMW sales ","description":"This animated bubble chart visualizes BMW sales volumes from 2010 to 2024 across selected countries and car models. A play/pause control and checkboxes let viewers filter by region and model while a year counter animates the timeline. The visualization uses D3 v7's `d3.csv` to load data, `d3.select` for DOM selection, and `d3.rollups` for grouping, rendering SVG bubbles whose size corresponds to sales figures.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1789737b4d2b4e8d897c94ff1e8c3774?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
