This is absolutely awesome. Such a good job well done! The search is fast! The sidebar is a great feature. I also love how you highlight the repositories you search for and draw red lines between things.

I found my journal repositories in the "Land of Node" in "Frontartia". I am surprised by that because I didn't realise I was associated with the node community!

I am so impressed with your visualization, it is intuitive and interesting the different communities of GitHub.
