# XWUIChartArea

An area chart block (9 variants) backed by `XWUIChart` that fills the region under each line to emphasize cumulative magnitude and compare totals across categories. Provide named `series` of `{ x, y }` points and select a `block` (1-4) and `size` preset; legend and grid auto-toggle per block unless overridden.
