FAQ

Why Another Git Graph Library?

There are numerous JavaScript/TypeScript libraries for rendering Git graphs (including GitGraph.js and Mermaid). I could not find one that had the features I needed (and some had bugs). What I created supports the following:

• Rendering branch names at the tip of the branches (vs the top of the branches)
• Rendering HEAD
• Supporting git amend
• Allowing the graph to be rendered incrementally while not moving commits around
• Supporting showing command-line arguments for each transition
