# XWUIChartLine3D

A 3D line chart backed by `XWUIChart` (rendering through the `@xw3d` layer when available) that lifts trend lines into a rotatable depth view for comparing multiple series in space. Provide named `series` of `{ x, y }` points and pick a `block` (1-4) variant plus a `size` preset; legend and grid auto-toggle per block unless overridden.

## Basic Usage

Two named monthly series - `Series A` (30→64) and `Series B` (22→52) across Jan-Jun - drawn as 3D trend lines.
