A tool for visualizing relationships between subreddits.

This program uses a dictionary of which users posted in which subreddit to build a similarity matrix and tries to cluster the subreddits in a tree-like structure, in which each node contains similar subreddits.

In order to fill the tree, K-means clustering algorithm is used recursively, first on the whole group of subreddits, then on any one of the clusters that exceeds a fixed amount of items.

The results are then visualized using d3.js and can be found here.

Data about which users posted in which subreddit is temporarily stored into the 'partial' folder and currently contains only data from October, November and December 2016.
