# XWUIChartTimeline

A timeline chart: a fixed-type wrapper around `XWUIChart` (`type: 'timeline'`) that lays
out one or more named `series` of `{ x, y }` points along a horizontal time axis, with
configurable line styling (`lineWeight`, `lineStyle`, `lineArrows`) and optional depth
stacking via `stackSeriesInZ`. Pass a `block` preset (1-4) and `size`
(`sm` / `md` / `lg`). Use it to chart sequences of dated events or activity
streams and compare several timelines side by side.

## Basic Usage

Two named series of monthly values arranged along a shared timeline at the md size preset.

## Product Launch Milestones
