This example visualizes car manufacturer sales data for the first six months of the year as an interactive 3D bar chart. The chart renders multiple series of bars using the `d3-x3d` library, which integrates D3.js with X3DOM for WebGL-based 3D graphics. It loads CSV data via `d3.csv`, parses monthly values for each manufacturer, and binds the data to the chart component. The visualization uses `d3.scaleLinear` for axes and supports rotation and zoom through the X3D scene.
