# XWUIChartSurface3D

A 3D surface chart: a fixed-type wrapper around `XWUIChart` (inner type `surface3D`) that projects a grid of values into a three-dimensional surface with depth, so peaks and valleys in a two-variable function stand out. Pass `{ series }` (rows of `{ x, y }`) plus a `block` preset (1-4) and `size`. Use it for terrain-like data where a 3D perspective conveys shape better than a flat heatmap.

## Basic Usage

Two series (Series A and Series B) of six monthly values, Jan through Jun, treated as grid rows and projected at medium size into a three-dimensional surface whose peaks and valleys gain depth.

## Ocean Floor Bathymetry

Seabed depth soundings from three parallel survey lines, stacked in Z and projected as a rotated 3D surface so the central trench reads as a clear valley.

## Reactor Temperature Field

Temperature readings across radial positions for three concentric sensor rings, projected as a steeply rotated 3D surface so the hot core falling off toward the edge stands out in relief.
