Looks neat! But it can use a better clustering approach when the map is zoomed out, the crowed arrows doesn't communicate much apart from their is activity, maybe some approaches could be to not show arrows at high level only connecting lines with maybe the arrow collapse into a lesser short form like how google maps collapse icons at higher zooms to small does and the trick is to add a heavy white stroke which adds a nice separation when it gets crowded, just some 2 cents. But nice work man!
