For humans, hierarchies are easier to think about and easier to format. But you're right: sometimes you really want to express your structure in a more general graph. And format it more graphically. For me the most obvious examples are: state-machines and entity-rln diagrams (and, for example, showing how your C-structs point to each other and how you're using std containers and ownership). Thanks for pointing out that what I really want is a way to create/edit a graph.
