It was really nice to see how different classes lead/connected to others. This was helpful because it makes it easier to think of the concentration as a unit of related classes rather than a bunch of different ones, and it was nice to see how other people have connected them together.
The two main things that I think could help make it more clear would be a key to the different colors and the courses they represent (it becomes clear eventually, but this would still be useful), and a way to search for/find a specific class' bubble, which would make it easier to start/continue the process.
One other feature that would be really useful would be to consider adding some way to visually highlight classes that haven't been pinned but maybe should be. Like classes that are linked to more than one bubble already pinned. Maybe this could be something like: pinned bubbles are biggest (as they already are), then any unpinned bubbles that are connected to multiple pinned ones are big, then unpinned bubbles that are linked to just one pinned one are slightly smaller, and bubbles that aren't linked to any pinned ones are smallest (as they currently are). As it is right now, it is possible to find the bubbles that multiple of my pinned ones link to, but it's kind of difficult. Something visual would make it much simpler to notice these as potential classes to look further into.
