I had wanted to build a website like this as a hobby, except not limited strictly to mathematical concepts. I wanted to build a graph of the skills/concepts you’d need to understand electrical impedance, fix an air conditioning system, bake bread reliably.
One source of information could be course syllabi, which describe a progression of topics and their prerequisites.
Rather than be the authority on what concepts must precede others, I envisioned making a system that could represent different educational approaches: not every educator agrees that Calculus I ought to be a prerequisite for studying Physics I. Not all bread recipes use yeast.
I had a hard time finding a good domain for this effort. “Tree of knowledge” dot TLD was taken.
