Hi, welcome to the community. While you are discovering Roassal, can you try to memorize moments where something didn’t work just because you didn’t know a simple rule? For example if you specify edges in a graph wilder before specifying nodes, the edges will not be added. To help people with this kind of problems I created a rule that detects if the “edges:” message is sent before the “nodes:” message, and warns about it. If you come up with more issue like the one I described, your project can be also to add Roassal-speciffec rules that help users to avoid mistakes while using Roassal.

Cheers.
