# XWUIChartColumn

A column chart: a fixed-type wrapper around `XWUIChart` that draws one vertical bar
per category so values are easy to compare by height; it is the vertical sibling of
the bar chart. Pass `series` of `{ x, y }` data plus a `block` preset (1-4) and `size`
(`sm` / `md` / `lg`); the shared block config also exposes legend, grid,
axis, data-label, and tooltip-formatter toggles. Use it to compare a value across a
handful of discrete categories.

## Basic Usage

Two monthly `{ x, y }` series fed to the column renderer at the md size preset,
drawing grouped vertical bars per month.
