Graph Visualization to Supplement Spaced Repetition

Looking for ways to improve my ability to reference my extensive notes (5k nodes and climbing rapidly). I have been toying with exploratory data analysis (namely using orange) and wonder if there are any good workflows for using advanced analysis to review or guide your quests for knowledge.

Mainly just curious to see what other people might have found useful in this space.

My current workflow is just to send everything to anki and letting that manage all my reviews and stuff but I’d like to beef it up a bit.
