A 3D scatter plot displays Toyota car data, plotting price, tax, and mileage for one series of markers, while a second series shows price, tax, and miles per gallon. The visualization uses Plotly’s `scatter3d` trace type within a `Plotly.newPlot` call, rendering interactive markers with adjustable opacity and line styling. Data is loaded via `d3.csv` from a remote GitHub-hosted CSV file, and the layout collapses the chart margins to zero. The plot compares vehicle cost and efficiency metrics across two distinct attribute combinations.
