Forked from Scatter Plot of BMW volume of sales with Hover
This animated bubble chart visualizes BMW sales volumes across global markets, plotting each model as a circle whose size reflects total sales for a given year. The visualization cycles through years from 2010 to 2024, with a large year label updating as the animation progresses. Users can toggle country filters via checkbox controls or pause the animation with a play/pause button. Built with D3.js v7, the chart uses `d3.rollups` for data aggregation, `d3.scaleSqrt` for bubble sizing, and SVG elements with animated transitions. Hovering over a bubble reveals detailed sales information via a tooltip.
