This 3D scatter plot visualizes truck mileage in relation to height and weight. It reads data from a CSV file containing values for Height (feet), Weight (tons), and Mileage (mpg), rendering each data point as a black circle. The chart is created with Plotly’s `scatter3d` trace, while D3.js (`d3.csv`) handles the remote data loading. Axis titles are color-coded, and margins and font styles are customized through the layout object passed to `Plotly.newPlot`.
