This animated bubble chart visualizes BMW model sales volumes across six global regions from 2010 to 2024. The visualization uses an SVG-based scatter plot where bubble size represents total sales volume, with each model assigned a distinct color and each region mapped to a representative country. Controls include checkboxes for filtering countries and models, plus play/pause and reset buttons. Built with D3 v7, the visualization uses `d3.rollups` for data aggregation, a linear animation interval for year progression, and smooth transitions for bubble movement and scaling.
