This interactive scatterplot compares North American and European sales for the top 200 game-platform records by global sales, with each dot representing a game and a dashed diagonal line indicating where sales are equal. The visualization uses D3 v7 to render SVG circles, with axes scaled linearly to a shared domain. Hovering over a dot triggers a tooltip displaying detailed sales breakdowns across regions. The chart animates smoothly as users interact, and data comes from a CSV file loaded via `d3.csv`.
