This example visualizes car manufacturer sales data for six months (July through December) as an interactive 3D bar chart. The bars represent monthly values for each manufacturer, rendered in a three-dimensional space using the x3dom library. The chart is created with d3-x3d’s `barChartMultiSeries` component, populated with CSV data parsed via d3.csv, and scales are defined using d3.scaleLinear. The visualization combines D3 v5 for data handling and DOM manipulation with x3dom for the 3D rendering engine.
