Git log history graph: How to use the visualization in the Log tool window

Question

How does the Git log history graph in the Log tab of the Git tool window work, and what does clicking on the nodes or lines do?

Answer

The Git log history graph is a visual representation of commits in the repository and the relationships between them. Branches and merges are rendered as colored lines and nodes connecting commits.

Interacting with the graph

• Clicking a node or a section of the graph collapses or expands that part of the commit history. Linear segments and parts that do not contain merges are typically hidden by default to simplify the view, especially in repositories with many commits and interweaved branches.
• Selecting a commit displays its details — including the branches that contain it — in the right-hand pane (bottom right) of the Git tool window.

Working with commits in the Log tab
