# Showcase

The flagship tour of `XWUIChartNestedDonut`: session share by device drawn as a ring with a hole,
how slice count changes readability, the data label / legend / title furniture, whole-ring
gradient and pattern fills via `series.style.fill`, the size scale and block presets, plus the
isometric projection and loading skeleton. Each instance mounts into its own fresh child div,
since an XWUI component clears its container on construct.
