Microservices to Workflows: Evolution of Jet's Order Management System

I think one of the most interesting pieces here is the visualizer!

Quite often, we end up building systems that rely on complex DAGs, but without a way to visualize them. GraphViz only works up to a certain size, and you lose most ability for interactivity with them.

I'm curious if anyone recognizes if any components of that visualizer are open source -- I'd love to dig in deeper.
