# FIR Tree
> Visualize Kotlin's Frontend Intermediate Representation (FIR) and Control Flow Graphs (CFG) right in your IDE
### Available at [JetBrains Marketplace](https://plugins.jetbrains.com/plugin/23270-fir-tree)
This plug-in helps you to understand the way the K2 Kotlin compiler represents the code internally.
- Adjustable resolution phase (the last one, `BODY_RESOLVE`, is the default),
- Click on a node in the tree to select it in the editor,
- Non-visible nodes are shown in italics and slightly grayed out,
- Visualize the control flow graph of a declaration.
Here's the outcome for this piece of code, fully resolved.
```kotlin
package function.equality
import kotlinx.coroutines.*
fun increment(x: Int) = x + 1
```
