# XWUIChart2DHistogram

A 2D histogram: a fixed-type wrapper around `XWUIChart` that bins paired data into a
grid and shades each cell by frequency, showing where observations concentrate
across two variables. Pass `series` of `{ x, y }` data plus a `block` preset (1-4)
and `size` (`sm` / `md` / `lg`). Use it when a scatter would overplot and
you want binned density instead of individual points.

## Basic Usage

Two series of monthly values fed to the 2D histogram renderer at the medium size
preset.

## Response-Time vs Payload

API requests binned by response time and payload size, with most traffic concentrated in the fast-and-small corner.

## Home Price vs Living Area

Property listings binned by price and square footage, the diagonal ridge tracking price rising with size.
