Using a pre-made layout solution would indeed be optimal, no reason to re-invent wheels. Apart from the layout, we'd get the rest for free from neo4j spatial and surrounding technologies.
This would be a separate visualization tool, with an ability to let clients explore massive graphs via a browser that, afaik, is not currently available. There is a reason to let, for instance, neo4j webadmin ship with a visualization tool. Just as the table format is a natural way to show relational database data in relational database management tools, a visualized graph is a natural way to show neo4j data. The problem we've wrestled with is that the web based graph visualization solutions available have trouble rendering large graphs. I'm not sure this would be a good solution to that particular problem, but it is a stab at solving the problem of showing huge, dynamically rendered graphs on the web.
