This dashboard presents BMW sales data from a CSV file, showing annual sales volume by model through an interactive stacked bar chart. A region filter updates summary cards, insights, and secondary charts for price trends, top models, regional breakdown, and sales classification. Built with D3 v7, the visualization uses `d3.stack`, `d3.scaleBand`, and `d3.scaleLinear` for the main chart, with interactive hover tooltips that dim non-hovered bars and display model, year, and sales details via a custom tooltip utility.
