# XWUIChartHeatmapMatrix

A heatmap-matrix chart variant backed by `XWUIChart` that lays out a full row-by-column matrix of color-coded cells, well suited to correlation grids and any dense table where value is read from hue. Supply one named `series` per matrix row, each carrying its cells as `{ x, y }` points (column label and value), then choose a `block` (1-4) and `size` preset.

## Basic Usage

Five named rows, each with seven randomized cell values, laid out as a 5x7 matrix of colored cells.
