An animated bubble chart visualizes BMW sales volumes across global markets from 2010 to 2024, with bubble size encoding sales figures for each model and country pair. The visualization updates year by year, showing sales trends over time. Interactive hover tooltips reveal precise details, while checkboxes filter markets and clicking legend items isolates specific models. Built with D3 v7, the chart uses d3.rollups for data aggregation, d3.scaleSqrt for bubble sizing, and d3.csv for loading the dataset, with SVG rendering and smooth animations between years.
