# XWUIChartSeasonalPlot

A seasonal plot: a fixed-type wrapper around `XWUIChart` that overlays each cycle (year,
week, day) on a common axis so repeating seasonal patterns line up and become easy to
compare. Pass your data as `series` of `{ x, y }` values plus an optional `block` preset
(1-4) and `size` (`sm` / `md` / `lg`); the shared block config also forwards
legend, grid, axis, data-label, and tooltip toggles. Use it to reveal seasonality that a
straight time line would hide.

## Basic Usage

Two named series of monthly values overlaid as seasonal cycles at the md size preset.
