# loader

The `loader` command loads data from a data source, data sink, or dataset into a dataframe in the notebook kernel memory.

## Syntax

```
loader
```

## Parameters

1. Click the button of the source type: **Data Sources**, **Data Sinks**, or **Datasets**.
2. From the drop-down list, select the source name.
3. Click the **Load Table** button.

Data is loaded into an in-memory dataframe, and a preview of the data is displayed on the screen. The loaded dataframe is set as the current working dataframe. Many of the visualization commands work on the current working dataframe.
