This bar chart displays global video game sales by genre, using data from Kaggle. It shows total sales in units for categories like Action, Shooter, and Platform, with bars rendered as SVG rectangles. The chart implements axes, labels, and a mouseover interaction that changes bar color. It uses d3.scaleBand, d3.scaleLinear, d3.axisLeft, and d3.axisBottom to construct the visualization, with animated color transitions on mouseout via D3 transitions.
