# Showcase

The flagship tour of `XWUIChartLine`. It walks the four block presets, the sm / md / lg size scale, the stroke and marker options, the axis polish hooks (unit, tick labels, custom formatters), hover interaction with the tracking crosshair, and the smooth curve and declarative annotation support.

It closes with a revenue dashboard: three regions smoothed on one large canvas with grid values, month captions and a target reference line.
