# XWUIChartStreamgraph

A streamgraph: a fixed-type wrapper around `XWUIChart` that stacks series as flowing bands around a central baseline (rather than a flat axis), producing an organic ribbon whose thickness shows each series' magnitude over x. Pass `{ series }` plus a `block` preset (1-4) and `size`. Use it for the evolution of many categories over time where overall composition and ebb-and-flow matter more than exact values.

## Basic Usage

Two series (Series A and Series B) of six monthly values, Jan through Jun, rendered at medium size as two flowing bands around a center baseline whose thicknesses swell across the months.
