A scatterplot displays video games from a CSV dataset, plotting critic scores against release years. Each point is colored by genre and its size encodes millions of units sold. The chart uses D3 v7 APIs including `d3.csv`, `d3.select`, `d3.scaleLinear`, and `d3.extent` to load and process data, map quantitative and categorical variables to position, hue, and area, and render the marks as SVG shapes.
