# Showcase

A full tour of `XWUIChartDrilldown`: the four block presets, the three block sizes, all four vertex marker styles, and the stroke weight, dash pattern and arrowhead controls. It closes with the grid and label toggles, pseudo 3D with per-series Z planes, the loading skeleton, and a real-world revenue-by-region summary.

The summary level carries one series per top-level bucket, which is the view a drilldown opens from before descending to per-country detail.
