The Change History of the Git Repository from 2005-2021

The Change History of the Git Repository from 2005-2021

Recently I decided to continue my experiments visualizing the data produced by the software development process. This time I decided to dig into the git commit history of Git itself, with the goal of creating something interesting and creative that still provides information about the subject matter.

This visualization is a radial representation of all changes stored in the Git git repository from inception to the end of 2020. Time flows clockwise and outward, starting from the first commit on 7 April 2005, until 31 December 2020. Circles represent the net lines of code added to the project on a single day.

It was a fun exercise and I’ll probably try to apply this approach to some other popular open source projects. I hope you enjoy it!
