Nice work. This would have been a nice tool to use when i was working with Neo4j. We had to roll our own for what we needed.<p>Some minor feedback since I know it's just a demo... but I think it would be more intuitive if when you "X" (remove) the facets in the search bar, the resulting nodes are removed too. I know this could get tricky given you can click a node to expand it, so you aren't visualizing only what was searched on - but some may find it confusing why removing the facets doesn't do anything.
