Hello, I got a question. Is there any way to match and show graph difference? For example, I have an original graph and also a modified graph. This modified graph is generated by adding or removing a few nodes and relationships from the original one. Is there any way to find what nodes and relationships were modified? These 2 are different graphs. Hence I don't have any changing history or log to analyze. The way I come up with is to check each node's id and also its relationships, and see if they exist in the other graph. Any other ways? Thanks!
