Visualizing the Git data model

Posted 2020-11-07 Programming.log - a place to k

I wrote a small tool git-graph.py over the weekend which can be used to generate the object graph of a Git repository. The primary purpose is to help Git learners better understand the Git data model through visualization. You can experiment with various git operations (e.g., add/delete/edit files or directories, merge branches, etc), commit, then run this tool to see what happened to the data in the .git directory under the hood.
