The Git graph helps developers visualize and understand the flow of Git operations, making it easier to discuss and share Git branching strategies.

Mermaid enables real-time rendering of the Git graph through commands like merge, checkout, branch, and commit.

Example:

gitGraph
    commit
    commit
    branch feat-1
    commit
    commit
    checkout main
    branch feat-2
    commit
    commit
    merge feat-1

In this example, we start by creating two commits on the main branch. We then create a new branch feat-1 and make two commits on it. Next, we switch back to the main branch and create a new branch feat-2, making two commits on it. Finally, we merge the feat-1 branch into main.

The resulting graph shows the flow of these operations, with each branch and commit represented by a node. The merge command creates a new node that combines the changes from both branches.
