The Sprint Graph is a tool for planning and tracking projects, from small-scale projects to epic, feature-complete ones. It provides the ability to view how deeply-nested issues and subtasks are, as well as visualizing how those tasks are connected.

The Sprint Graph provides an interface to get insights into your issue history in much greater detail than before. It provides visualized lists of issues and subtasks that are connected with an arrow, indicating the flow of work. 

If you're looking to get a better understanding of the subtasks of an issue, the Sprint Graph is your ideal tool for that. You can drag subtasks around the graph to rearrange their positions on the issue, so you can make sure you have the right balance of issues and subtasks. It also provides an interface for viewing your project's dependency flow. You can view the subtasks and issue you're working on from any issue, any story, or any sprint.
