```python theme={null}
def __init__(
    self, content: matplotlib.figure.Figure | io.BytesIO | bytes
) -> None:
```

<Expandable title="arguments" defaultOpen>
  <ResponseField name="content" type="matplotlib.figure.Figure | io.BytesIO | bytes" required>
    The content of the dashboard as a matplotlib figure or a png image as bytes.
  </ResponseField>
</Expandable>

## Example

Here's an example of creating a PNG dashboard using matplotlib:

```python theme={null}
from squirrels.dashboards import PngDashboard
from squirrels.arguments import DashboardArgs
import matplotlib.pyplot as plt
import polars as pl

async def main(sqrl: DashboardArgs) -> PngDashboard:
    # Get dataset
    df = await sqrl.dataset("sales_data")
    
    # Create matplotlib figure
    fig, ax = plt.subplots(figsize=(10, 6))
    
    # Plot data
    pandas_df = df.to_pandas()
    pandas_df.plot(x='date', y='revenue', ax=ax)
    ax.set_title('Sales Revenue Over Time')
    ax.set_xlabel('Date')
    ax.set_ylabel('Revenue ($)')
    
    # Return as PngDashboard
    return PngDashboard(content=fig)
```
