I need a "Decision Tree" diagram. It is published as text and vectors, so taking the published one and editing it beats redrawing it.
## What this diagram says
Lays out a decision as branches on conditions, every path ending in an outcome.
## When it fits
- Turning an operational judgement into something anyone can follow without guessing.
- Naming a default branch so a case outside the conditions still lands somewhere.
## When it does not
- When a node has more than one parent: this profile allows only one.
- When the decision loops back over time — use State Machine.
## What this kind validates
- Validates a single root, one parent per node, acyclicity, the default branch, and that every leaf is an Outcome.
## What it does not
- Does not check that the conditions cover reality, only that a default exists.
## What you can take
- https://design-vault.pages.dev/designs/diagram-decision-tree/samples/decision-editorial-publication/decision-tree.drawio
- https://design-vault.pages.dev/designs/diagram-decision-tree/samples/decision-editorial-publication/decision-tree.png
- https://design-vault.pages.dev/designs/diagram-decision-tree/samples/decision-editorial-publication/decision-tree.svg
- https://design-vault.pages.dev/designs/diagram-decision-tree/samples/decision-editorial-publication/diagram-spec.json
- https://design-vault.pages.dev/designs/diagram-decision-tree/samples/decision-editorial-publication/layout.json
- https://design-vault.pages.dev/ai/assets/diagram-decision-tree.json
## What you can edit
The published `.drawio` is uncompressed XML. Open it in draw.io and edit it, or diff it as text.

Operations this kind accepts through the engine: alignNodes, distributeNodes, moveNode, resizeNode

This kind accepts only geometry operations — it has none that change meaning.
## Writing a new one
A `diagram-spec.json` can be written against the schema below.

- https://design-vault.pages.dev/schemas/diagram-spec.schema.json
- https://design-vault.pages.dev/schemas/layout.schema.json
## What cannot be done here
**A spec you write cannot be validated here, and `layout.json` cannot be computed here.** The generator that does both is not published; what is published is the artifacts, the inputs and the schemas. Place the geometry yourself, or hand the spec to someone who has the engine.
## Licence
The diagram and its inputs are CC BY 4.0 — carry the credit when you use them.
