# XWUIChartContourSurface

A contour-surface chart variant backed by `XWUIChart` that renders a gridded value field as a shaded surface with iso-level contours, useful for reading the shape of a continuous field across two axes at a glance. Supply one named `series` per grid row, each carrying its cells as `{ x, y }` points (column label and height), then pick a `block` (1-4) and `size` preset.

## Basic Usage

Five named rows, each with seven randomized cell values, rendered as a 5x7 contoured surface.

## Heated Plate Temperature Field

A steady-state temperature field in Celsius across a metal plate heated near one corner, shaded as a surface whose contours fall off from the hot spot to the ambient edges.

## Drug Combination Response Surface

A pharmacology dose-response surface of cell viability across two drug concentrations, dipping from full viability in the untreated corner to near-total kill where both doses are high.
