This interactive bar chart displays video game sales across different platforms, allowing users to switch between global, EU, JP, NA, and other regional sales metrics via a React dropdown menu. The visualization uses d3.scaleBand and d3.scaleLinear to map platforms and sales values to SVG rectangles, with axes rendered through custom React components and d3 formatting. Data comes from a Kaggle video game sales dataset, loaded asynchronously via d3.csv and processed through React's useState and useEffect hooks.
