# Basic Usage

Builds an XWUIChartRadialTree by calling `new XWUIChartRadialTree(container, data, { size: "md" })` with a `nodes` hierarchy (Root -> A/B/C, where A holds the leaves A1=10 and A2=20) and `series: []`; because the component uses the `'radial'` graph layout, that tree is wired into nodes that radiate outward from the root.
