# XWUIChartDensityCurve

A density-curve chart: a fixed-type (`type: 'densityCurve'`) wrapper around
`XWUIChart` that draws a smooth estimated-density curve (a KDE-style outline) over the
`series` instead of discrete bars. Pass `series` of `{ x, y }` values plus a `block`
preset (1-4) and `size` (`sm` / `md` / `lg`); legend, grid, axis, and
line-style toggles come from the shared block config. Use it to show the shape of a
distribution as a continuous curve.

## Basic Usage

Five generated rows of values drawn as smooth density curves at the medium size
preset.

## API Response Time Distribution

A single right-skewed density curve over measured API latencies, with an SLA threshold marked on the x-axis.

## Adult Height Distribution

Two overlapping bell curves comparing the height distributions of two populations.
