# XWUIChartMarketEquilibrium

A market-equilibrium chart: a fixed-type wrapper around `XWUIChart` (resolving to the `line`
renderer) for economics-style supply-and-demand curves, where the crossing point marks the
equilibrium price and quantity. It inherits the shared chart block contract - construct it
with `(container, data, conf_comp)` where data is `{ series, title? }`, then pick the `block`
variant and `size`, and optionally toggle legend / grid / axes / data labels, opt into 3D,
and forward tooltip and tick formatters to the underlying chart. Use it to plot intersecting
demand and supply lines with no per-variant configuration overhead.

## Basic Usage

Two named series plotted as intersecting curves at the md size preset.

## Coffee Supply and Demand

## Housing Market Demand Shift

A supply curve with two demand curves shows how a demand shock moves the equilibrium outward.
