Nice to stumble over this thread.

I'm not sure if Flint is the right tool for me. I'd like to have a tool that expresses code in visual form for me. For example, right now I need to reverse engineer some code for debugging purposes.

I already found out there are three tasks:

    * Task one fills task two's queue and waits for an event to get notified
    * Task two reads from its queue, forwards elements to task three's queue.
    * Task three reads from its queue and sends a success/fail message back to task two's queue
    * Task two then notifies the waiting task one.

Which ML tools suited best for that?

Seems a bit more like https://mermaid.js.org use cases!
