# XWUICardChartKPISparkline

A compact KPI-card sparkline backed by `XWUIChart` that pairs a headline metric with a small inline trend line, sized for dashboard tiles that need a quick read on direction rather than a fully axis-labelled chart. Provide named `series` of `{ x, y }` points and pick a `block` (1-4) variant plus a `size` preset; legend and grid auto-toggle per block unless overridden.

## Basic Usage

Two named monthly series - `Series A` climbing 30→64 and `Series B` climbing 22→52 across Jan-Jun - rendered as paired sparklines.
