Nice project.
Interactive visualizations usually make these kinds of concepts much easier to grasp than static diagrams.
I'm curious whether you've tried this with students or engineers who are completely new to power systems, and what kind of feedback you've received.
Thank you! We've tried it with engineers from other fields and it helped them understand the basic concepts needed to build software for e.g. grid operators.
Especially the visual admittance matrix has been useful (we'll publish a blog post how power flow and the admittance matrix works soon) as an introduction to the relevant algorithms.
