This 3D scatter plot visualizes the relationship between length, breadth, and the resulting area and volume for squares and rectangles. Two sets of markers are rendered: red circles for area and green diamonds for volume, each positioned in three-dimensional space based on the CSV data. The example uses Plotly’s `Plotly.newPlot` method to create the `scatter3d` traces, with data loaded via D3’s `d3.csv` function. Axis titles and marker styling are configured through the layout object.
