I used to build my own little wiki / knowledge graph as a fun project to see what it was capable of. You feed it a topic and ask it to return a list of topics that are related to the parent topic. Repeat for each child topic, set a max depth and you can generate a topic tree about anything. Always asking for it to use JSON as the output. I then had GPT-4 write an encyclopedia style entry for each child topic with nice formatting and links to actual wikipedia when possible.
