## Classes

### `LabelDiver` <sup>[https://github.com/PrefectHQ/prefect/blob/main/src/prefect/server/events/schemas/labelling.py#L6](https://github.com/PrefectHQ/prefect/blob/main/src/prefect/server/events/schemas/labelling.py#L6)</sup>

The LabelDiver supports templating use cases for any Labelled object, by
presenting the labels as a graph of objects that may be accessed by attribute.  For
example:

```python theme={null}
diver = LabelDiver({
    'hello.world': 'foo',
    'hello.world.again': 'bar'
})

assert str(diver.hello.world) == 'foo'
assert str(diver.hello.world.again) == 'bar'
```
