This example displays car manufacturer sales data for the first six months of the year as a 3D bar chart, with each manufacturer represented by a cluster of monthly bars. The visualization is rendered using the d3-x3d library, which integrates D3.js with X3D scenes. The code loads CSV data via `d3.csv`, transforms each row into a multi-series format, and passes the parsed data to a `d3.x3d.chart.barChartMultiSeries()` component. The chart is attached to an HTML `div` using D3’s `select` and `datum` methods, with styling applied directly to the container.
