Pure functions (functions that will always produce the same output (given the same input) without affecting anything outside their scope) help in this design.

Concurrent programming requires practice and more practice. Go makes it easy once you understand the basic primitives. Diagrams can help you to understand the possible flow of data, but the best way of understanding it all is simply to practice.
