# XWUIChartParallelSets

A parallel-sets chart backed by `XWUIChart` that shows how categorical records split and recombine across dimensions as flowing ribbons, used to trace composition and shared membership. 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 series - `Series A` (30→64) and `Series B` (22→52) across Jan-Jun - drawn as flowing category ribbons.
