This 3D scatter plot visualizes the Iris dataset using Three.js for WebGL rendering and D3.js for data processing and scaling. Colored circles represent different Iris species, mapped to petal length, petal width, and sepal width coordinates. The scene automatically rotates via `requestAnimationFrame`, and users can pan to rotate the view using D3's `select` and `zoom` interaction. The code generates circle sprites from canvas textures with `CanvasTexture` and `SpriteMaterial`.
