This animated bubble chart visualizes BMW sales volumes across global markets from 2010 to 2024, with circles positioned by year and scaled by sales volume. The visualization cycles through years automatically, updates the large year display, and uses d3.rollups to aggregate the CSV data by country, model, and year. Hovering over bubbles reveals detailed tooltips, while checkboxes filter by market and clicking legend items highlights specific models. The implementation uses D3 v7 with SVG rendering, d3.scaleSqrt for bubble sizing, and d3.axis for the grid and axes.
