I am working with a graph in Memgraph that has weighted edges. I’d like to set up a trigger that will keep track of the total weight of all edges in the network.

Here is an example of the graph structure:

• Nodes represent different cities.
• Edges represent roads between these cities.
• Each edge has a weight that signifies the distance between two cities.

For instance:

(A)-[10]->(B)
(B)-[20]->(C)
(A)-[15]->(C)

In this example:

• The edge between A and B has a weight of 10.
• The edge between B and C has a weight of 20.
• The edge between A and C has a weight of 15.

The total weight in this example would be 45.
