This example shows regional video game sales as a 3D multi-series bar chart, comparing North America, Japan, and global sales across the top-selling titles. The visualization uses the `d3.x3d` library to render the bars in an X3D scene, with `d3.csv` loading the dataset and a custom row parser structuring the data for the chart. The chart is created by calling `d3.x3d.chart.barChartMultiSeries()`, and the code updates the displayed data using D3’s selection and `datum` methods.
