A 3D scatter plot displays the classic Iris dataset, plotting sepal length, sepal width, and petal length as black markers with subtle gray outlines. The visualization uses Plotly’s `scatter3d` trace type within an interactive WebGL-rendered scene, offering rotatable and zoomable exploration. Data is loaded asynchronously via D3’s `d3.csv` from a remote GitHub gist, with axes labeled accordingly. The layout minimizes margins and sets explicit axis titles, while marker size, opacity, and line styling are configured directly in the trace definition, creating a clean, focus-driven view of the multivariate flower measurements.
