@brief Creates an edge from vertex from to vertex to in collection edgeCollectionName

graph.edgeCollectionName.save(from, to, data, options)

@PARAMS

@PARAM{from, string, required} _id attribute of the source vertex

@PARAM{to, string, required} _id attribute of the target vertex

@PARAM{data, object, required} JSON data of the edge

@PARAM{options, object, optional} See collection documentation

@EXAMPLES

@EXAMPLE_ARANGOSH_OUTPUT{generalGraphEdgeCollectionSave1} var examples = require("@arangodb/graph-examples/example-graph.js"); var graph = examples.loadGraph("social"); graph.relation.save("male/bob", "female/alice", {type: "married", _key: "bobAndAlice"}); ~ examples.dropGraph("social"); @END_EXAMPLE_ARANGOSH_OUTPUT

If the collections of from and to are not defined in an edge definition of the graph, the edge will not be stored.
