This example shows an interactive 3D bar chart comparing profits for multiple motels across the years 2017–2021. The visualization uses the `d3.x3d.chart.barChartMultiSeries` API to render bars as three-dimensional objects within an X3DOM scene. Data is loaded asynchronously from a CSV file using `d3.csv` and parsed into a hierarchical format with each motel containing five yearly values. Users can rotate and explore the plot, which includes animated transitions as the dataset loads.
