Are there any issue trackers that organize issues in a flowchart/graph-structure style? Something where each task is a node, and its relationships to other tasks, such as being a child issue, dependency, blocker, etc is shown by the arrows/edges.
As a developer, I would find this type of interface very useful. It would make it easy to triage, find tasks, and make sense of how everything fits together. Contrarily, swim lanes do not have this advantage. While they can show task distribution across organizational processes, their linear lists do not illustrate task relationships and are time consuming to sift through.
My two-part question is, are there any such flowchart-based issue trackers available? And as a developer, how useful do/would you find this?
