Neo4j automate graph change over time

Question

Is there a way (query) or tools that enable auto playback of a graph change over time?

E.g. over time, new nodes or old nodes might be removed.

For instance:

• Graph 1: Node A is connected to 4 others nodes
• Graph 2: Node A is connected to 3 others nodes
• Graph 3: Node A is connected to 6 others nodes

A "playback" or query to automatically shows Graph 1 to 3 periodically.

Any suggestion is appreciated! :)
