This example presents a 3D bar chart comparing the yearly profits of the top five motels in the USA across four years (2017–2020). The visualization loads CSV data from a GitHub gist, parses it into a multi-series format, and renders it using the d3-3d library alongside X3DOM for WebGL-based 3D output within a React context. The chart is built with D3 v5 utilities like `csv`, `select`, and `scaleLinear`, and the bars are generated via the custom `d3.x3d.chart.barChartMultiSeries` component, offering an interactive perspective on the profit trends.
