git graph not working

[shashwatj07]

Installed git-graph after satisfying all the dependencies. However, on running the git graph command, I get this on a keyboard interrupt after waiting for a minute.

$ git graph

Can you please try to install from GitHub and run the pytest command to check if it succeeds or fails similarly ? Thanks

I tried it again. It appears that it only works with repositories with a very small number of commits.

Normally the graph should be created whatever the repository size. However for large graph rendering, GraphViz dot can encounter difficulties and hang forever.
