Each dot is a subreddit. "countries" are clusters of usually related subreddits. Relationship is determined based on Jaccard Similarity (users who post to A also post to B)<p>This was my hobby over past few years. I collected ~176 million unique pairs `(user, subreddit)` of comments, computed jaccard similarity, clustered a graph, performed a layout, created a webgl renderer and streaming svg parser, and today releasing it to the wild. Hope you enjoy it!<p>* The source code for the rendering is available here: <a href="https://github.com/anvaka/map-of-reddit" rel="nofollow">https://github.com/anvaka/map-of-reddit</a><p>* To change the map - go here <a href="https://github.com/anvaka/map-of-reddit-data" rel="nofollow">https://github.com/anvaka/map-of-reddit-data</a>
