This bar chart shows the global sales of video games by genre, ranking categories like Action and Shooter by their total sales in millions. The visualization uses D3 v6 to load CSV data from a GitHub gist, and renders the chart as an SVG with animated transitions. It employs `scaleBand` for the x-axis and `scaleLinear` for the y-axis, with axes generated by `axisBottom` and `axisLeft`. Bars are filled steelblue and change to orange on mouseover, using D3’s selection and transition APIs.
