Yes, I think it can be hard to find the information, and I have posted here on it before.
EDIT: So, I saw your recent post more than a week after I answered this other post, but just now I noticed the post dates, it looks like your post was online a day before I answered the other post, so you couldn't have seen my response. I know I did some searches on the topic at the time to see if someone else had already answered it, but never ran across your post, or I would have responded to it as well. Curious..
So that is great news! As far as I knew Gephi was dead (it has been stale for a long time now), exciting to hear there is work on it, I've long felt it is one of, if not the best viz tool, (but with a lot of room for improvement) It can viz larger graphs, and I really enjoy using it to get a sense of the graph neighborhood characteristics. Cytoscape (if you have a lot of patience and time) is pretty nice as well. The first time I tried Cytoscape I gave up, it can be that frustrating, but once you get going it can create some beautiful visualizations. It has two neo4j plugins, so far both work equally well, you can query neo4j directly and display the results in Cytoscape. They each take a little different configuration information, and you need to get one of the plugins from GIT (to patch an issue), so if you try them and run into any issues let me know, I use both plugins.
