# Showcase

The flagship tour of `XWUIChartRidgeline`. It walks the four block presets, the sm/md/lg canvas scale, every display toggle (legend, grid, axis spines, title, grid values, data labels), the `interactive` hover mode, the isometric `use3D` transform with `rotation3D`, and the loading skeleton.

It then builds the ridge wall itself: one card per city over a shared month axis, followed by a large canvas whose plotted ridge is swapped by buttons through `setData()`.
