This interactive 3D scatter plot visualizes car sales data across three consecutive years (year20, year21, year22) as points in three-dimensional space. Each marker’s position corresponds to a vehicle’s metrics in those years, colored blue with black outlines and 0.8 opacity. The visualization uses the Plotly JavaScript library (via `plotly-2.9.0.min.js`) and loads CSV data through d3.csv from a GitHub gist. The code defines a scatter3d trace with explicit axis titles, then renders it into a div using `Plotly.newPlot`.
