AWS CodeCommit Introduces Commit Visualizer Graph View

You can now view visual representations of the commits made to your AWS CodeCommit repositories. The Commit Visualizer is a graphical view which helps you see the sequence of commits to a branch, the relationship between parent and child commits, and merges into the branch. You can filter by branch or re-render the graph by a specific commit. You can click each commit to view details such as commit ID, parent ID(s), date, committer name, and commit message.
