@brief Select all vertices connected to the edges selected before.
graph_query.vertices(examples)
Creates an AQL statement to select all vertices for each of the edges selected in the step before. This includes all vertices contained in _from as well as _to attribute of the edges. The resulting set of vertices can be filtered by defining one or more examples.

@EXAMPLES
To request unfiltered vertices:
@EXAMPLE_ARANGOSH_OUTPUT{generalGraphFluentAQLVerticesUnfiltered} var examples = require("@arangodb/graph-examples/example-graph.js"); var graph = examples.loadGraph("social"); var query = graph._edges({type: "married"}); query.vertices().toArray(); ~ examples.dropGraph("social"); @END_EXAMPLE_ARANGOSH_OUTPUT
To request filtered vertices by a single example:
@EXAMPLE_ARANGOSH_OUTPUT{generalGraphFluentAQLVerticesFilteredSingle} var examples = require("@arangodb/graph-examples/example-graph.js"); var graph = examples.loadGraph("social"); var query = graph._edges({type: "married"}); query.vertices({name: "Alice"}).toArray(); ~ examples.dropGraph("social"); @END_EXAMPLE_ARANGOSH_OUTPUT
To request filtered vertices by multiple examples:
@EXAMPLE_ARANGOSH_OUTPUT{generalGraphFluentAQLVerticesFilteredMultiple} var examples = require("@arangodb/graph-examples/example-graph.js"); var graph = examples.loadGraph("social"); var query = graph._edges({type: "married"}); query.vertices([{name: "Alice"}, {name: "Charly"}]).toArray(); ~ examples.dropGraph("social"); @END_EXAMPLE_ARANGOSH_OUTPUT
