Paste git log output and see a visual branch graph with commit history and merge points.
Git Log Visualizer turns pasted Git history into a node-and-lane view of commits, forks, and merge points. It is intended for output that preserves commit identifiers and topology, especially `git log --graph` output. The pasted text is the complete evidence: the tool does not inspect your repository or recover revisions excluded by the original command, and the text is processed in the browser. The usual surprise is that a drawn lane is not necessarily a named branch. Git records parent relationships; branch names are movable refs shown only when the log includes them.
A compact source is `git log --graph --oneline --decorate --all`. Its graph characters express lane connections, abbreviated object names identify commits, subjects describe them, and decorations can expose refs such as branches and tags. A merge must be understood from its multiple-parent relationship, not merely from the word `Merge` in its subject. Plain hashes and subjects may not provide enough topology.
Each recognized commit record becomes a point in the displayed history, while connecting lanes represent the ancestry supplied by the log. A multi-parent junction marks a merge commit. The vertical sequence reflects the supplied revision walk; horizontal placement routes connections and is not a permanent branch assignment. Ref decorations label commits but do not create additional commits or change their parent relationships.
`git log --graph --oneline --decorate --all` is a compact choice when you want topology, readable subjects, and ref names. Remove `--all` if only history reachable from the current starting point matters. The visualizer cannot compensate for commits excluded before pasting, so use a revision range, path filter, or count limit only when that narrower view is intentional.
No. A Git commit stores parent links, not an enduring original-branch field, and branch names are movable refs to commits. The visualization can show ancestry and any ref decorations present in the pasted text. A lane may represent a side line of development, but its horizontal position alone cannot establish that line's former branch name.
