GGobi VS git-sizer

• Interactive Data Visualization
  GGobi provides a highly interactive graphical user interface that allows users to explore multivariate data through dynamic and interactive plots.
• Multiple Linked Plots
  The tool supports multiple linked views, allowing users to see the relationship between different dimensions in real-time as selections in one plot update the others.
• Open Source
  GGobi is open-source software, which means it is freely available to download, use, and modify, promoting transparency and community-driven improvements.
• Integration with R
  It integrates well with R via the `rggobi` package, allowing users to leverage the strengths of R for data manipulation and GGobi for visualization.
• Supports Multiple Data Formats
  GGobi can import data from various file formats including CSV and XML, making it flexible for users who have data in different formats.

Possible disadvantages

• Steep Learning Curve
  The software can be complex for new users, requiring time to become familiar with its features and interface.
• Outdated User Interface
  The graphical user interface may appear outdated and less intuitive compared to more modern visualization tools.
• Limited Documentation
  Documentation and support resources are limited, which can make troubleshooting and learning the software more challenging.
• No Recent Updates
  GGobi has not seen significant updates in recent years, which might limit its capabilities in keeping up with modern data visualization requirements.
• Requires Installation
  Unlike some web-based visualization tools, GGobi requires installation on a local machine, which might not be convenient for all users.

• Comprehensive Repository Analysis
  git-sizer analyzes many different dimensions of a Git repository including commit count, tree size, blob size, history depth, and reference counts, providing a holistic view of repository health and potential scaling issues.
• Easy to Use
  The tool is simple to run with minimal setup—just execute it within a git repository—and it produces clear, human-readable output that highlights potential problem areas without requiring complex configuration.
• Identifies Performance Bottlenecks
  It helps identify specific issues that could degrade Git performance, such as excessively large blobs, deep history, large trees, or too many references, which is valuable before migrating or scaling repositories.
• Open Source and Maintained by GitHub
  Being an official GitHub project, it benefits from credibility, community trust, and ongoing maintenance, and it is well documented with clear explanations of what each metric means.
• Useful for Pre-Migration Checks
  It's particularly helpful for teams migrating repositories to new platforms or consolidating repos, as it flags potential issues that could cause problems during migration or with hosting providers' limits.

Possible disadvantages

• No Automatic Remediation
  git-sizer only identifies and reports issues but does not offer any built-in tools or automated processes to fix problems like large blobs or excessive history depth—users must use separate tools like BFG Repo-Cleaner or git-filter-repo.
• Output Can Be Overwhelming for Beginners
  While detailed, the output includes many metrics and threshold levels that may be confusing for users unfamiliar with Git internals, requiring some learning curve to fully interpret results.
• Limited to Local Analysis
  The tool analyzes a local clone of the repository, so it requires users to have a full local copy of the repo (or at least enough history) to get accurate results, which can be time-consuming for very large repositories.
• No Real-Time Monitoring
  It functions as a one-time analysis tool rather than providing continuous or real-time monitoring of repository health, requiring manual reruns to track changes over time.
• Command-Line Only Interface
  The tool lacks a graphical user interface, which may be less accessible for users who prefer visual dashboards or are less comfortable with command-line tools.

• Anscombe's Quartet

  It's clearly hard, but there are tools for doing exploratory visualization of high-dim data. GGobi http://ggobi.org/ and all the ones that arrange points but try to get local neighborhoods correct (t-sne, umap, et al.). - Source: Hacker News / about 1 year ago

• how to keep github repos small?

  Also there’s a cool project from GitHub you can use to help understand the size of git’s objects in your git repo https://github.com/github/git-sizer. This might help you determine what the best cloning strategy could be. Source: almost 5 years ago
