The visualization presents BMW's global sales from 2018 to 2025 through four linked charts: annual revenue bars, year-over-year growth lines for revenue and units, a sunburst model-mix, and a portfolio-shift chart. It uses d3.v7's `scaleBand`, `scaleLinear`, `axisLeft`, `axisBottom`, and `line` APIs to render SVG graphics. Monthly CSV data is aggregated into yearly totals, showing revenue trends, growth correlations, and the growing share of electric models alongside dominant SUVs.

Making Meaning of BMW Sales Volume Bar Chart

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.

BMW SALES DASHBOARD

This interactive BMW sales dashboard uses a tabbed interface to switch between an animated bubble chart of annual sales trends (2010–2024), a bar chart of total sales by model, a map with proportional bubbles for regional distribution, and a stacked bar chart classifying high versus low sales volume by region. The annual chart employs `d3.scaleSqrt` for bubble sizing, `d3.rollups` for data aggregation, and `d3.scaleBand` for model legends, with checkbox filters and play/pause controls. The other charts use `d3.rollups`, `d3.scaleBand`, `d3.scaleLinear`, and `d3.geoMercator` projection with `d3.geoPath`. All tooltips and bars rely on declarative `join` operations, sourcing data from a CSV.
