I have a lot of books. I also claim to be good at building some structure out of disorder. So I experimented with building a more visual way of understanding the themes in my library. I just created a list of categories for my books, dumped it into chat and asked it to generate the graph based on semantic similarity of the themes.
It kind of worked? It seems like there are 5 distinct higher order categories that I could call: technology, biological+philosophical intelligence, fiction and criticism, biology, and investing and startups.
