This example visualizes a 3D scatter plot of body measurements, plotting Height, Weight, and BMI as points in three-dimensional space. The data comes from a CSV file loaded via `d3.csv`, and each marker is rendered as a black circle with defined opacity and size. The visualization is built using the Plotly.js `scatter3d` trace type and the `Plotly.newPlot` API, with axis titles styled in distinct colors. The layout configures margins and scene axes to frame the data within a minimal HTML page.
