This 3D scatter plot visualizes the classic Iris dataset, mapping petal length, petal width, and sepal width to the x, y, and z axes, with species determining point color. The visualization supports interactive rotation via panning and features continuous auto-rotation animation. It renders circular sprites using Three.js on a WebGL canvas with HiDPI scaling, while D3 handles data parsing, linear scales, and ordinal color mapping via `d3.csv`, `d3.scaleLinear`, and `d3.scaleOrdinal`. The zoom interaction is configured to constrain rotation within vertical limits.
