# `ChartJson`

Type, in `@jr2/orchestrator/src/chart.ts`. The signature of an export, or a type that it names, names this type. The [Authoring surface](../authoring-surface.md) page lists each export. This type is not an export of `@jr2/orchestrator`, so a workflow module does not import it by name.

```ts
type ChartJson = string | number | boolean | null | ChartJson[] | { [key: string]: ChartJson };
```

Plain JSON.
