# XWUIChartNightingale

A Nightingale (polar / rose) chart backed by `XWUIChart` that draws each category as a wedge radiating from the centre, with magnitude encoded by radius - a circular take on the bar chart for cyclical data. 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 monthly series - `Series A` (30→64) and `Series B` (22→52) across Jan-Jun - drawn as radiating rose wedges.

## Wind Direction Rose

Each compass direction is a wedge whose radius is how often the wind blew from there.

## Sales by Month

Monthly revenue mapped to equal-angle wedges so the seasonal peak balloons outward.
