2.1 Using Sample Data for Graph Analysis
The rpm installation of the graph server provides you with sample graph data in
                /opt/oracle/graph/data directory.
               
The bank_graph folder contains data that represent the
            vertices and edges of a graph in bank_nodes.csv and
                bank_edges_amt.csv files respectively. You can import the graph
            data from these .csv files into the database. You can then create a
            graph for querying and analyses.
