- Rendering a simple tree like this would work just as well, if better, in text only format (like the output of the "tree" command on linux) : https://justpaste.it/6r9un
- The classification also seems a bit manual and arbitrary.
Maybe giving each node a weight would make d3 worth using ? Maybe scrap the subscribers of each subreddit, and make a force directed "map of reddit nsfw" ?
Your skills seem wasted on this if you're good at d3
