# Showcase

The flagship tour of `XWUIChartOriginDestinationFlowMap`: origins in the left column, destinations in the right column and one curved ribbon per flow, built from `data.nodes` and `data.links`.

It explains the ordering rule that decides which column a place lands in (the node list is split down the middle), shows how link value becomes ribbon thickness, and walks the sm / md / lg size scale, the four block presets and the title, legend and loading chrome.
