Mermaid supports two graph orientations: **Left-to-Right** (default) and **Top-to-Bottom**.
Mermaid supports three graph orientations: **Left-to-Right** (default), **Top-to-Bottom**, and **Bottom-to-Top**.
You can set this with either `LR:` (for [**Left-to-Right**](#left-to-right-default-lr)) or `TB:` (for [**Top-to-Bottom**](#top-to-bottom-tb)) after `gitGraph`.

```
### Bottom to Top (`BT:`) (v\<MERMAID_RELEASE_VERSION>+)
In `BT` (**Bottom-to-Top**) orientation, the commits run from bottom to top of the graph and branches are arranged side-by-side.
To orient the graph this way, you need to add `BT:` after gitGraph.
Usage example:
```mermaid-example
gitGraph BT:
commit
commit
branch develop
commit
commit
checkout main
commit
commit
merge develop
commit
commit
```
```mermaid
gitGraph BT:
commit
commit
branch develop
commit
commit
checkout main
commit
commit
merge develop
commit
commit
```
## Parallel commits (v10.8.0+)
Commits in Mermaid display temporal information in gitgraph by default. For example if two commits are one commit away from its parent, the commit that was made earlier is rendered closer to its parent. You can turn this off by enabling the `parallelCommits` flag.

In `BT` (**Bottom-to-Top**) orientation, the commits run from bottom to top of the graph and branches are arranged side-by-side.
To orient the graph this way, you need to add `BT:` after gitGraph.
Usage example:
```mermaid-example
gitGraph BT:
commit
commit
branch develop
commit
commit
checkout main
commit
commit
merge develop
commit
commit
```
## Parallel commits (v10.8.0+)
Commits in Mermaid display temporal information in gitgraph by default. For example if two commits are one commit away from its parent, the commit that was made earlier is rendered closer to its parent. You can turn this off by enabling the `parallelCommits` flag.
