This interactive dashboard uses D3.js v7 to visualize BMW sales data from 2010-2024, displaying key metrics, a timeline of sales across six markets, top-selling models, regional distribution, fuel type comparisons, and yearly trends. The visualization employs SVG rendering with animated transitions, tooltips, and annotations that highlight peak sales periods and best-selling models. Data loaded from a CSV file is aggregated and processed using D3 rollups to compute summary statistics.
