# XWUIChartDial

A dial chart: a fixed-type (`type: 'dial'`) wrapper around `XWUIChart` that shows a
value as a needle sweeping across a circular gauge, like a speedometer. Pass `series`
of `{ x, y }` values plus a `block` preset (1-4) and `size` (`sm` / `md` /
`lg`). Use it for a single headline reading against a range, such as a KPI, score,
or utilization level.

## Basic Usage
