This bar chart shows BMW sales volumes over time, grouped by year and colored by the region. Each year displays a cluster of bars representing different global markets, such as the USA, Brazil, and China. Users can click on a country in the legend to highlight its bars in a specific color while dimming others to grey. Built with D3.js v7, the visualization uses `d3.rollups` to aggregate sales data from a CSV file and `d3.scaleOrdinal` for color mapping, with a tooltip providing detailed data on hover.
