# Showcase

The flagship demo for `XWUIChartHeatmapOnMap`. It steps through the four block presets, the size scale, the per-cell value callouts, the chrome toggles (grid, axes, legend, title) and the loading skeleton, using a city zone grid and a rainfall grid.

It ends with a real demand layer: four city bands by six zones shaded by Friday-night pickup count, the view a dispatcher would use to move supply.
