You can't really have pointers to data with protobuf, only actual
data. You might do something like
message Node {
optional string name;
repeated string neighbor;
}
message Graph {
repeated string names;
repeated Node nodes;
}
And use the name (or some other unique identifier) to figure out which
Node a particular neighbor is.
