package dependency
to DPDK.

    doc: add inbuilt graph nodes data flow

    Added diagram to depict the data flow between inbuilt
    graph nodes.

    In order to avoid graphviz package dependency to DPDK
    documentation, manual step added to create a svg file
    from the dot file. The details for the same is documented
    in graph_inbuilt_node_flow.svg as a comment.
