Upon researching some cloud based graph database, I came across fairly old, but fancy neo4j sandbox and brand new AG cloud express.Neo4j Sandbox( provides user-friendly tutorial (the 'sometimes annoying' pop up guide) and fun datasets to play around with within the cloud service. Downside is since there seem to be a lot of data, the loading of project and node dragging is a bit laggy.AG Cloud Express ( seems recently developed and its interface is rather simple, but really easy to use for first time user. Not a lot of datasets though, simple seems to be the key here, which is also better in this situation since this service seems faster compared to Neo4j sandbox.In terms of usability, which of the two cloud services do you all think is better? Are easy/fast/simple one of the traits you look for in a cloud service?
