This example visualizes the relationship between height, weight, and body fat percentage using a 3D scatter plot, with each point representing an individual from a BMI dataset loaded via `d3.csv`. The plot uses Plotly’s `scatter3d` trace type, rendering blue markers with grey outlines and an opacity of 0.8. Axes are labeled for each variable, with red title fonts, and the layout minimizes margins to focus on the data. The code calls `Plotly.newPlot` to draw the chart into a `<div>` element, relying on D3 for CSV parsing and Plotly for interactive 3D rendering.
