virajput/breakscale ? reverse-engineered prompt

Build me a web app that lets me design a simple distributed system on a canvas, connect the pieces together, then turn up the traffic and watch it start to struggle in real time.

I want to be able to add things like servers, load balancers, caches, queues, workers, databases, rate limiters, and circuit breakers, then see the effect on latency, queue depth, throughput, retries, and failures as the system gets overloaded. It should feel like a teaching tool, so when I click around I can inspect what each number means and why it matters.

Include a handful of example setups I can load quickly, like a basic single server, a cache setup, a retry storm, and a circuit breaker scenario. Make the simulation deterministic so the same setup behaves the same way each time. If you need to look up current docs or best practices online, feel free to.
