# Showcase

A flagship tour of `XWUIChartProductionPossibilityFrontier` built on a guns-against-butter tradeoff: an efficient frontier, a recession year that sits inside it, and the outward shift that follows investment. The sections walk through the four block variants, the three size presets, stroke and marker styling, the chart furniture toggles (grid, grid values, axis spines, legend, data labels), hover interactivity, the pseudo-3D transform, and the loading skeleton.

Every chart mounts into its own freshly created host element, because an XWUI component clears the container it is constructed into.
