A 3D scatter plot of the classic Iris dataset, colored by species (setosa, versicolor, virginica) and plotted using sepal length, sepal width, and petal length. The visualization, rendered with Plotly's WebGL scatter3d type, displays each flower as a marker with a purple outline and a custom colorscale mapping species to distinct hues. Data is loaded via d3.csv, with species labels converted to numeric color indices for the marker’s color attribute. The plot emphasizes three-dimensional separation of the flower measurements, with axis titles and colored grid backgrounds provided.
