This example shows a bar chart of global video game sales by genre, using data from a CSV file. D3 version 6 loads the data with `d3.csv`, maps it with `scaleBand` and `scaleLinear`, and renders SVG rectangles with axes via `d3.axisLeft` and `d3.axisBottom`. Bars animate color changes on hover using `selection.on` and `transition.attr`, shifting from steelblue to orange and back.
