This example visualizes three wine sample groups in a 3D scatter plot, comparing measurements of malic acid, ash, and alcalinity of ash. Each group is represented by a distinct color—red, blue, and green—with semi-transparent markers to reveal overlapping points. The code loads CSV data via `d3.csv` from a GitHub gist and renders the interactive plot using Plotly’s `Plotly.newPlot` function with a `scatter3d` trace type. Axis titles label each dimension, and a legend identifies the wine samples.
