Interactive diagrams of Rx Observables

In plain words

Interactive Diagrams of Rx Observables is a tool for learning and working with Rx functions. It provides interactive visual representations of how Observables behave, allowing users to see data streams and transformations in action. The platform helps developers understand reactive programming concepts, build Observable sequences, and test different Rx operations. It's designed for anyone learning or working with reactive extensions and needs to visualize how asynchronous data flows through their code.

I'm a software engineer by trade, and with conventional tools, I often times struggle to explain flows of data in complex software systems. I got inspired by video games like The Incredible Machine and Factorio, as in some ways, software systems tend to become Rube Goldberg-esque machines ;) As a side quest, I also wanted to craft diagrams faster than text-based tools (ex: mermaid), as I am always forgetting their…
