/diseases/charts/regions
/diseases/charts/regions
Returns **distinct region options** that appear in the **GIDEON chart catalog**, for building chart filters or autocompletes. Pair with **`GET /diseases/charts/countries`** for country pickers scoped the same way.
Each item has **`id`** (numeric id for chart filters), **`source`** (`countryregion` or `state`), and **`name`** (label). Use **`source`** to decide how to pass the id into **`GET /diseases/charts`**: `state` rows correspond to the **`states`** query parameter; `countryregion` rows correspond to **`countryregions`**.
All query parameters are **optional**; omitting filters returns a larger set (still limited to regions that appear on charts in the catalog).
#### **Query parameters**
| Name | Required | Description |
| --- | --- | --- |
| `countries` | No | Comma-separated country codes. |
| `diseases` | No | Comma-separated disease ids. |
| `q` | No | Prefix filter on the resolved region name. |
