This post introduces two effective methods for visualizing Git repositories using treemaps, enhancing developers’ ability to comprehend repository structures. The first method utilizes `git-truck`, an open-source tool that allows for quick generation of visualizations through simple commands. The second approach involves creating custom visualizations by integrating the GitPython and Plotly libraries, achievable in just a few lines of code. Both techniques aim to help developers identify heavily modified files and areas of high collaboration, thereby facilitating easier navigation through unfamiliar codebases.
