This example shows car manufacturer sales data for the first six months of the year in an interactive 3D bar chart. The visualization displays multi-series data with each manufacturer represented by a group of bars for January through June, using the `d3.x3d` library to render the scene in X3D. The code loads CSV data asynchronously via `d3.csv`, parses rows into a multi-series format, and attaches the dataset to a chart component built with `d3.x3d.chart.barChartMultiSeries()`. Styling and interaction rely on D3 v5 selection and layout APIs, with the 3D output rendered through the x3dom framework.
