This interactive dashboard visualizes BMW model sales performance from 2010–2024, using a stacked bar chart to compare sales volumes across regions and years. Users can filter by geographic region, sort bars by total sales or specific models, and click bar segments or legend items to highlight individual models with smooth opacity transitions. Built with D3.js v7, the visualization uses SVG rendering with animated transitions and interactive tooltips, reading data from a CSV file containing model, region, year, and sales volume information.
