This example visualizes car manufacturer data for the first six months as a 3D bar chart, with each series grouped by gender and showing values for height, weight, age, and body fat. The chart is rendered using the `d3.x3d` library, which combines D3.js v5 with X3DOM for WebGL-based 3D graphics. Data is loaded asynchronously from a CSV file via `d3.csv`, parsed with a custom row function, and fed into a `barChartMultiSeries` component. The visualization also utilizes D3 scales and axes for layout and quantitative mapping.
