{"version":"1.0","type":"rich","title":"BMW World map sales","description":"This stacked bar chart shows BMW sales volume by year, broken down across five regions (Asia, North America, Europe, South America, Middle East, and Africa), with regions color-coded and clickable to toggle their visibility by turning bars white. The visualization aggregates the CSV data using `d3.rollups` to sum `Sales_Volume` per year and region, then renders the result as stacked bars with `d3.stack`, scales via `d3.scaleBand` and `d3.scaleLinear`, and includes axes, grid lines, and an interactive legend for filtering regions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d7449972766845259ef12dbe10ddd73d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
