Hello VizHub
An interactive 3D scatter plot and grid is rendered with D3.js, using randomly generated data points and a coordinate grid. The visualization displays a 3D space where points are colored using `d3.scaleOrdinal` and the `d3.schemeCategory20`, with a y-axis scale and labels. Users can click and drag to rotate the 3D scene, with the rotation logic driven by `d3.drag()` events and `_3d()` API calls for grid, point, and line strip shapes. This example demonstrates the use of D3’s 3D extension and custom event handling for dynamic, animated rendering.
