# XWUIChartRadialStackedBar

XWUIChartRadialStackedBar is a thin wrapper around XWUIChart that fixes the chart `type` to `'radialStackedBar'`, drawing bars that radiate from a common center with series segments stacked along each spoke. Pass `{ series }` data and configure it with `block` (1-4, clamped) and `size` (`'small'` | `'medium'` | `'large'`). Use it when you want the circular form of a radial bar chart but also need to show how parts compose each total per category.

## Basic Usage

This example passes a single "Share" series of five slices (A=35, B=25, C=20, D=12, E=8) to the constructor at `size: "md"`, drawing one stacked radial bar per category around the center.
