Reach tree
Everything one key can reach.
Definition · Updated Nov 2, 2026
A reach tree starts from one key or account and branches to every system it can touch, marking write and read access with what each lets it do. Use it for API key reviews, service accounts and access audits.
Pay once. Every update included.

What the key can do there (REVERSES CHARGES, EVERY ORDER).
One data object in the sample’s shape: a root, systems and access per link. The docs page lists every field and links its JSON Schema; the sample data comes with the component, so you can start from it and swap in your own.
Series take the preset’s data colours in order, and states such as up, down or warning take its status colours. Change the preset in Figma or in code to recolour every chart at once.
XS, S, M and L, in light and dark. Each size is laid out again from the data, so text and lines keep their size.
Yes. It plays in when it scrolls into view, and when the data changes every mark moves from its old place to its new one. With reduced motion on, it does not move.
Yes. The Figma component comes with Figma and Complete, the React component with Code and Complete.
Ask for it by name. The MCP server tells the agent what data it needs and runs the same command: npx shadcn add @chartory/reach-tree. You review the diff.
