# Showcase

The flagship tour of `XWUICardChartKPISparkline`. It walks the four block presets, the sm / md / lg size scale, the stroke and marker options (weight, dash pattern, end arrow, vertex style), the card chrome that strips a sparkline down to a bare trend line, and the interactive and loading states.

It closes with a four card KPI wall: revenue, signups, churn and latency, each mounted into its own child div.
