This interactive 3D scatter plot visualizes the Iris flower dataset, mapping petal length, petal width, and sepal width along the three axes, with color encoding species. Built with Three.js and D3, it uses sprites rendered via WebGL for circular points and supports both user-controlled panning and an automatic slow rotation animation. The scene is constructed with Three.js `Scene`, `PerspectiveCamera`, and `WebGLRenderer`, while D3 utilities like `csv`, `scaleLinear`, and `scaleOrdinal` handle data loading and mapping.
