+- Provides access to information, and operation:
+    - `Graph.vertices`, `graph.edges`, `graph.triples`: access property
+    - `Graph.degrees`: Access connected edges: Provides a tuple with
+      (`vertexId`, `degree` of each vertex)
+    - `Graph.connectedComponents`: each of the connected components of the graph
 - Pregel-like iterative graph traversals:
     - Number of iterations are needed
     - `mergeMsg`: Combine incoming messages to a single one
