This fork of a 3D scatter plot visualizes the Iris dataset, displaying two series of markers that map sepal length, sepal width, and either petal length or petal width. The visualization uses Plotly’s `Plotly.newPlot` to render a `scatter3d` chart inside a `div`, with data loaded via `d3.csv`. Each trace configures marker size, opacity, and line styling, while the layout removes all margins to focus on the plotted points.
