A CSV export is on the roadmap. Stay tuned!

Hey, you can do that already by selecting a reference node, then creating a "number of hops to reference node" filter with some parameter (eg. only show nodes that are less than X hops away from your reference node).

6 weeks? That's amazing! What is your stack? What were the technical challenges that came up? Have you considered open sourcing your project? Would be very interesting to see how the whole thing works!
