This 3D scatter plot visualizes two sets of monthly sales data, with one trace plotting April, May, and June values and a second trace plotting July, August, and September values. The chart uses Plotly's `scatter3d` trace type, rendered through the `Plotly.newPlot` function within the Plotly 2.9.0 JavaScript library. Data is loaded from a GitHub-hosted CSV file using D3's `d3.csv` method, and the layout removes all margins for a full-bleed display.
