SunburstChart
A hierarchy drawn as nested rings — each ring a level, each arc's sweep its
value. Feed it an adjacency list: id names each node, parent points at
its parent's id (blank or unknown ⇒ a root). value (optional) sizes a node
and label (optional) is its display name.
<SunburstChart data={org_tree} id="id" parent="parent" value="headcount" label="name" title="Headcount" />Note
SunburstChart needs an id/parent hierarchy, which the
semantic metric=/by= grammar can't express — so it takes
data={query} only. (For a metric split by one category, a
PieChart metric=/by= works.)

Same id/parent/value/label shape as TreeChart — Sunburst shows proportions, Tree shows structure. For a single-level part-to-whole use PieChart or TreemapChart. The rest are the shared chart attributes — see Charts.
