This example presents car manufacturer sales data for six months as an interactive 3D bar chart. It uses the D3.js `csv` loader to parse a remote CSV file into a multi-series dataset, which is then attached to a chart component created with `d3.x3d.chart.barChartMultiSeries`. The visualization leverages the d3-x3d bridge to render bars in an X3D scene, with D3's `scaleLinear`, `axisLeft`, and `axisBottom` handling the chart layout and axes within the HTML container.
