# Layouts
This page lists the available layout algorithms supported in Mermaid diagrams.
## Supported Layouts
- **elk**: [ELK (Eclipse Layout Kernel)](https://www.eclipse.org/elk/)
- **tidy-tree**: Tidy tree layout for hierarchical diagrams [Tidy Tree Configuration](/config/tidy-tree)
- **cose-bilkent**: Cose Bilkent layout for force-directed graphs
- **dagre**: Dagre layout for layered graphs
## How to Use
You can specify the layout in your diagram's YAML config or initialization options. For example:
```mermaid-example
---
config:
layout: elk
---
graph TD;
A-->B;
B-->C;
```
```mermaid
---
config:
layout: elk
---
graph TD;
A-->B;
B-->C;
```

# Tidy-tree Layout
The **tidy-tree** layout arranges nodes in a hierarchical, tree-like structure. It is especially useful for diagrams where parent-child relationships are important, such as mindmaps.
## Features
- Organizes nodes in a tidy, non-overlapping tree
- Ideal for mindmaps and hierarchical data
- Automatically adjusts spacing for readability
## Example Usage
```mermaid-example
---
config:
layout: tidy-tree
---
mindmap
root((mindmap is a long thing))
A
B
C
D
```
```mermaid
---
config:
layout: tidy-tree
---
mindmap
root((mindmap is a long thing))
A
B
C
D
```

## [Mermaid introduces the Visual Editor for Entity Relationship diagrams](https://docs.mermaidchart.com/blog/posts/mermaid-introduces-the-visual-editor-for-entity-relationship-diagrams)
