Freemind looks like tree rather than DAG. Almost all mind-mapping software uses tree structures. Even org mode can't gracefully do DAG. Still looking for that

Freemind looks like tree rather than DAG. Almost all mind-mapping software uses tree structures. Even org mode can't gracefully do DAG. Still looking for that simple-to-use free text tool that has a graph structure. Task Warrior comes close, but it hard to use for deep graphs. It's a major UX challenge. I personally use Flying Logic for this type of use case. Costs money though.
