3D Scatter Plot
This example visualizes monthly vehicle sales as a 3D scatter plot, comparing new and used sales volumes across two overlapping marker groups. The first trace plots New, Used, and Total Sales New; the second plots New, Total Sales New, and Total Sales Used, with gray and blue markers for contrast. Data is loaded from a CSV file using d3.csv, then rendered through Plotly’s scatter3d type with configurable marker size, opacity, and line styling. The layout removes all margins to maximize the plot area.
