A 3D scatter plot visualizes the relationship between Height, Weight, and Body Fat from a CSV dataset. The plot uses Plotly’s `scatter3d` trace with pink circular markers, and each axis is labeled with the corresponding variable. Data is loaded asynchronously via `d3.csv` from a GitHub gist, and the `unpack` function extracts each column into arrays for the x, y, and z coordinates. The layout defines axis titles and font styles, and `Plotly.newPlot` renders the interactive chart inside an HTML div.
