# XWUIChartPolarArea

XWUIChartPolarArea wraps XWUIChart with the chart `type` fixed to `'polarArea'`, drawing a single `{series}` of categories as equal-angle sectors radiating from a center, where each sector's radius encodes its value. Like a pie it is part-to-whole, but because magnitude maps to radius rather than angle it makes differences between categories easier to compare. Configure it with `block` (1-4, clamped) to pick the variant layout and `size` (`sm`, `md`, or `lg`) to set the dimensions.

## Basic Usage

This example renders a single five-slice "Share" breakdown (A=35, B=25, C=20, D=12, E=8) at medium size, with each category as an equal-angle sector whose radius reflects its value.

## Wind Direction Frequency

A wind rose mapping how many hours per year the wind blows from each of the eight compass sectors, with the dominant SW prevailing wind reading as the longest spoke.

## Monthly Rainfall

Average monthly rainfall wrapped around a twelve-month wheel, where the summer wet season swells the Jun-Aug sectors well beyond the drier winter months.
