This interactive bar chart visualizes the sales of video game genres across different global regions, using a dropdown menu to switch between sales metrics such as Global, EU, JP, NA, and Other Sales. Built with React and D3 v5, it renders SVG rectangles via the `Marks` component, with axes generated by custom `AxisBottom` and `AxisLeft` components. The data is loaded from a CSV file using D3’s `csv` function, and the chart scales the y-axis dynamically with `scaleLinear` and `format`.
