|
||
|
||
|
||
The [Kotlin Notebook Plugin for IntelliJ IDEA](https://plugins.jetbrains.com/plugin/16340-kotlin-notebook),
|
||
combined with Kotlin DataFrame, offers powerful data analysis capabilities within an interactive environment.
|
||
Here are the key features:
|
||
|
||
### Drag-and-Drop Data Files
|
||
|
||
You can quickly load data into `DataFrame` into a notebook by simply dragging and dropping a file
|
||
(.csv/.json/.xlsx and .geojson/.shp) directly into the notebook editor:

|
||
|
||
### Visual Data Exploration
|
||
**Page through your data**:
|
||
The pagination feature lets you move through your data one page at a time, making it possible to view large datasets.
|
||
|
||
**Sort by column with a single click**:
|
||
You can sort any column with a click.
|
||
This is a convenient alternative to using `sortBy` in separate cells.
|
||
|
||
**Go straight to the data you need**:
|
||
You can jump directly to a particular row or column if you want something specific.
|
||
This makes working with large datasets more straightforward.

|
||
|
||
|
||
### Drill down into nested data
|
||
When your data has multiple layers, like a table within a table,
|
||
you can now click on a cell containing a nested table to view these details directly.
|
||
This makes it easy to go deeper into your data and then return to where you were.

|
||
|
||
|
||
### Visualize multiple tables via tabs
|
||
You can open and visualize multiple tables in separate tabs.
|
||
This feature is tailored to those who need to compare, contrast, or monitor different datasets simultaneously.
|
||
|
||

||

|
||
|
||
|
||
### Exporting to files
|
||
|
||
You can export data directly from the dataframe into various file formats.
|
||
This simplifies sharing and further analysis.
|
||
The interface supports exporting data to JSON for web applications,
|
||
CSV for spreadsheet tools, and XML for data interchange.
|
||

|
||
|
||
|
||
### Convenient copying of data from tables
|
||
You can click and drag to select the data you need,
|
||
or you can use keyboard shortcuts for quicker selection
|
||
and then copy what’s needed with a simple right-click or another shortcut.
|
||
It’s designed to feel intuitive,
|
||
like copying text from a document, but with the structure and format of your data preserved.
|
||

|
||
|
||
### Rendering of images in the cell
|
||
|
||
Table widget can render `BufferedImage`s.
|
||
Given a column of images, right-click on the cell and click `View Image` in the context menu.
|
||
|
||
|
||
|
||
### Clickable URI links
|
||
|
||
String values starting with `https://`, `https://`, `file:/` are treated as clickable links that open, for example, your browser or file manager.
|
||
Click on the cell to trigger a toolbar to appear.
|
||
|
||
|
||
|
||
Clicking on `Open URL` or `Open File URI` for the first time triggers a notification with a link to `Settings` → `URL Click Settings`.
|
||
Choose what protocols should be allowed.
|
||
|
||
|
||
|
||
To get started, ensure you have the latest version of the Kotlin Notebook Plugin installed in IntelliJ IDEA,
|
||
and begin exploring your data using Kotlin DataFrame in your notebook cells.
