This bar chart displays the sales of video games by publisher, allowing users to select among global, EU, JP, NA, and other regional sales data from a dropdown menu. The chart uses D3 v5 scales and axes to map publisher names along the x-axis and sales values on the y-axis, with each publisher represented as a rectangular mark. Interactive elements include the dropdown for changing the sales metric and tooltips revealing exact values. The underlying data is loaded from a CSV file hosted on GitHub, processed with D3’s `csv` function, and the entire visualization is built using React components and SVG rendering.
