This stacked bar chart illustrates BMW’s global sales volumes across 11 vehicle models from 2010 to 2024, with a set of filter buttons that instantly repopulate the visualization for different geographic regions. Built with D3.js v7 and HTML, the chart aggregates data from a CSV file, using `d3.rollups` to sum sales per model and year, and renders the result as an SVG with smooth animations. Interactive hover tooltips reveal detailed yearly figures, while a separate statistics panel computes regional totals and top-performing models.
