This example displays a 3D bar chart of car manufacturer sales data for the first six months of the year, with each manufacturer’s monthly values rendered as a series of bars. It uses the d3-x3d library to generate the 3D scene, along with d3.v5 for data loading and parsing via `d3.csv`, and x3dom for rendering the X3D content in the browser. The code defines a `barChartMultiSeries` chart component, attaches it to a chart holder div, and populates it with data from a remote CSV file. The bars are positioned along categorical and temporal axes, with height encoding the numeric value.
