This example visualizes the revenue data from a CSV file as a 3D cube-based bar chart using Plotly. The chart’s `cubes3d` trace type maps product names to the x-axis and revenue values to both the y and z axes, with semi-transparent markers. It combines D3.js for CSV parsing and layout configuration, while Plotly.js handles the 3D rendering in an SVG container. The data originates from a GitHub-hosted CSV, and the visualization demonstrates a custom axis margin setup.
