We wrote this script to show how async functions can modeling and visualizing flows in a system. github 
Script logic creates nodes that run infinite loops trading Money for stuff.
As nodes trade with each other they also report to a function that reports state and accumulated flows. [⇒ Accumulation]
~
We simulate a micro economy where tom, dick and harry
are makers and users of stuff in a producer-consumer relationship.
github
We visualize total cash flows between the people and the organizations that represent costs for makers and reliable income for the users.

The simulation code creates cash flows into and out of the bank. A single cashflow() function alerts the viz as flows happen.
The visualization code accumulates total flows from each participant. Flows are converted to edges in a graphviz diagram updated immediately unless still busy with the previous update.
