# XWUIChartConfidenceIntervalSimple

A simple confidence-interval chart (point estimates with their confidence-interval
whiskers, in a stripped-down form): a fixed-type wrapper around `XWUIChart` that plots
each estimate as a marker and extends a whisker across its interval so the uncertainty
around every point is visible at a glance. Pass each line as a `series` of `{ x, y }`
values 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 when you want a clean, low-clutter view of estimates and their margins of error.

## Basic Usage

Two monthly series (Series A and Series B, Jan-Jun) plotted as point estimates with
their confidence-interval whiskers at the md size preset.
