High-level visualization of dependencies between releases Merged

I would like to make a high-level visualization of the dependencies between different releases, similar to the attached diagram.
In this example, I have two different product lines (A and B), each with multiple releases. The releases in these product lines require successful completion of several software, firmware and hardware building blocks. The dependency diagram shows that three product releases are dependent on the completion of the software OS 2.0 release and four product releases require release firmware FW 1.1 to be ready. I know that I can use the Releases >> Roadmap tab in the Aha! tool to define dependencies between features of different releases. However, I feel that the resulting Gantt chart is not always the most convenient visualization, especially if I want to demonstrate the high-level dependencies between different releases within a large organization like ours, without being burdened with the exact timing of each feature. So I would like to see this capability in the Aha! tool. Otherwise, I will still have to create this diagram in an external tool such as Excel.
