This 3D scatter plot visualizes the Iris dataset, mapping petal length, sepal length, and petal width onto the x, y, and z axes. Each flower sample appears as a single marker with semi-transparent points and subtle gray outlines. The visualization uses Plotly’s `scatter3d` trace type, loaded via the Plotly.js library, while D3.js fetches the CSV data from a GitHub gist. Margins are set to zero for a clean, full-canvas presentation, with no axes or labels configured.
