| Best use | For developers and small teams that want architecture and data-flow diagrams close to the repository and reviewable as text. Use it when relationships matter more than pixel-perfect placement; not for free-form marketing design or exact manual positioning. | Ideal for developers, data analysts, and operators who need to clean a CSV export, inspect JSON Lines, or summarize a large file from the terminal without starting a Python project. Use it for quick, repeatable file processing; concurrent transactions and advanced visual analysis still call for a database or complementary analytics tool. | For developers reviewing features as small changes and revisiting earlier steps. Start with a separate practice clone to learn working copies and Bookmarks; delay team adoption until compatibility with required Git tooling is checked. |
