This interactive 3D scatterplot visualizes the classic Iris dataset, encoding sepal length, petal length, and sepal width along three axes. Each point is colored by species, with a wireframe grid providing spatial reference. The visualization supports drag-based rotation to explore the data from any angle. Built with D3.js v4 and the d3-3d plugin, it projects 3D coordinates to SVG paths and circles, leveraging a drag behavior to update rotations and animate transitions. The Iris data is imported from an external CSV file.
