I've only worked with Akka Graph DSL to build some data pipelines or protocol stacks. And I've loved working with it!

The equivalent of atopile signal would be port with Akka I think. A combination of ports gives us a shape. A source shape is just one OUT port. A flow shape is one IN and one OUT port, etc.

I'm very new to electronics so I don't know if it makes sense, but connecting all these ports with directional arrows was really helpful to understand the data flow.
