# XWUIChartConfusionMatrix

A confusion-matrix chart variant backed by `XWUIChart` that renders predicted-vs-actual class counts as a colored grid, the standard way to inspect classifier accuracy and spot where labels are confused. Supply one named `series` per matrix row, each carrying its cells as `{ x, y }` points (column label and count), then pick a `block` (1-4) and `size` preset.

## Basic Usage

Five named rows, each with seven randomized cell counts, laid out as a 5x7 matrix grid.

## Handwritten Digit Classifier

An MNIST-style 5x5 confusion matrix for digits 0-4, with the bright diagonal marking correct predictions and off-diagonal cells exposing the most-confused pairs.

## Sentiment Classifier

A three-class review-sentiment confusion matrix where the heavy diagonal confirms accuracy and the Neutral row shows where neutral reviews leak into Negative and Positive.
