Distribution Charts display a pie and should return a plain object.

```python
from forestadmin.datasource_toolkit.context.agent_context import AgentCustomizationContext
from forestadmin.datasource_toolkit.decorators.chart.result_builder import ResultBuilder
from forestadmin.datasource_toolkit.interfaces.chart import Chart

async def books_by_author_country_chart_fn(
    context: AgentCustomizationContext, result_builder: ResultBuilder
) -> Chart:
    return result_builder.distribution({
        "validated": 100,
        "rejected": 100,
        "to_validate": 100,
    })

agent.add_chart("booksByAuthorCountry", books_by_author_country_chart_fn)
```
