# Showcase

XWUIChartBlocks is the shared base of the chart-block family and has no renderer of its own, so this showcase proves its `ChartBlockConfigBase` contract instead: one config object is handed unchanged to Bar, Line, Area and Scatter, and then each group of shared options is walked in turn.

It covers the block variant index, the shared size scale, the legend / grid / axis / data-label toggles, the line-family options (marker style, stroke weight, dash pattern), and the shared interactive and loading states.
