This visualization presents six months of car manufacturer data as an interactive 3D bar chart. It was built using the D3.js v5 library, along with the `d3-3d` and `d3-x3d` extensions, which leverage the X3DOM framework for browser-based 3D rendering. The chart is populated from a CSV file containing manufacturer-specific monthly values. The code assigns the parsed data to a `barChartMultiSeries` component, which is then attached to the HTML chart holder, displaying the multi-series bars in a three-dimensional space.
