This visualization displays global video game sales by genre, using a bar chart to compare units sold across categories like Action, Shooter, and Platform. The chart is built with D3 v6, using `scaleBand` for the x-axis, `scaleLinear` for the y-axis, and SVG rectangles for the bars. Bars animate their fill color to orange on mouseover and transition back to steelblue on mouseout. The data, sourced from Kaggle, is loaded as CSV and parsed, with axes and labels rendered via `axisBottom` and `axisLeft`.
