# Showcase

The flagship tour of `XWUIChartFrequencyPolygon`: two national age profiles overlaid on one
scale, a before/after quality-control comparison built with per-series stroke and marker styling,
the sm / md / lg size scale, the four vertex marker styles, the stroke weight and dash menu
(including the sketched filter), and the four block presets with the loading skeleton. Each
instance mounts into its own fresh child div, since an XWUI component clears its container on
construct.
