Using the Deployed Application

  1. Visit the Reddit Visualizer
  2. Search for your desired subreddit using the search bar or start exploring from the default subreddit (AskReddit).
  3. Click on subreddit nodes to expand that subreddit to see its connections.
  • Line weight represents connection strength
  • Node size represents subscribed members
  • Explanation of node colors is in legend in the bottom left-hand corner
  1. To find a path between two subreddits type a starting subreddit into the first search field and a destination subreddit into the second input, or simply search from the second input and use the current subreddit as the starting point.
  2. Use the "Expand subreddits" button to expand all nodes currently visible that have connections.
