# XWUIChartRidgeline

A ridgeline chart: a fixed-type wrapper around `XWUIChart` that stacks each series as a
slightly overlapping filled curve, like a range of mountain ridges, so you can compare the
shape of several distributions in a compact strip. 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 compare many distributions or time slices side by side.

## Basic Usage

Two named series of monthly values stacked as overlapping ridges at the md size preset.

## Monthly Temperature Distributions by City

## API Latency Distributions Across Versions

Three API releases shown as stacked latency-bucket ridges, lining up the legacy tail against the rewrite's tight peak.
