This 3D bar chart visualizes car manufacturer sales data for the first six months of a year. The visualization uses the d3-x3d library to render the bars in an interactive 3D space, with data loaded from a CSV file via the `d3.csv` API. The chart employs a multi-series bar layout, grouping months along one axis and manufacturers along another, while the `d3.axisLeft` and `d3.axisBottom` functions generate the chart’s axes. The scene is displayed within an HTML page using the x3dom rendering engine.
